Overview
What is the Charles University Third Faculty of Medicine entrance exam?
The Third Faculty of Medicine (LF3) sets its own entrance examination for its English-taught General Medicine programme in Prague. There is no shared national Czech admission test behind it, and Charles University's five medical faculties each write their own paper; LF3's is the narrowest of the three Prague faculties by subject list and the only one that tests just two subjects.
The written part is 60 questions: 30 Biology and 30 Chemistry, weighted exactly equally, with four options per question and exactly one correct answer. Each question is worth one point, so the written part scores between 0 and 60. There is no Physics section, no logic or reasoning block, and no general-knowledge component. The expected level corresponds to the Czech grammar-school framework, and the test is taken electronically on the applicant's own laptop or other device.
Admission runs in two parts. The written test does not admit anyone on its own: the Dean sets the minimum number of points needed to proceed to the second part on the basis of that year's first-part results, and the second part is a separately scored interview worth 12 to 62 points, covering interpretation of a popular-scientific text, general overview, independent judgement, communication skills, motivation and an evaluator recommendation. Two consequences follow, and they shape everything below: the number you need is not published because it does not exist until the cohort has sat the paper, and roughly half of what LF3 assesses is never touched by the written test at all.

LF3's official admissions pages were updated for the 2027/2028 cycle on 12 October 2026 and now give the same deadline, Prague dates, application fee and tuition as Charles University's admissions record for the programme, published in its admissions system, which also confirms the written test's structure, option count and 0–60 point range. Note also that LF3 publishes a separate Czech-language document for its Czech-medium programme describing a 90-question Biology, Physics and Chemistry paper; that is a different exam, and none of its figures apply to the English-taught test described here. IvyTest re-checks lf3.cuni.cz/3LFEN-819.html and the admissions record, and updates this guide when either changes.
Structure
Charles University LF3 Entrance Exam format
Two parts of 30 questions each, 60 in total, every question worth one point. Each carries four options, A to D, with exactly one correct answer, confirmed across all 60 items of LF3's official 2025 sample test. The one thing the table cannot give you is a time column: LF3 publishes no duration anywhere, so pacing per question cannot be derived from official material.

| Section | Questions | Weighting | Suggested time |
|---|---|---|---|
| Biology | 30 | 50% (30 of 60) | *see the note below the table |
| Chemistry | 30 | 50% (30 of 60) | *see the note below the table |
- LF3 publishes no time limit for the written test at all: not per section and not overall
Content
Question and subject breakdown
Two subjects, thirty questions each, exactly equal in weight. With no Physics, no reasoning section and no general-knowledge block, there is nowhere on this paper to offset a weak subject with a strong one: an even performance across both is worth more here than on any other Charles faculty's test.
Biology
50%LF3's official premedical Biology syllabus runs to forty numbered headings with no higher-level grouping, spanning living systems and bioenergetics, prokaryotes, viruses, eukaryotic cells, DNA and gene expression, the cell cycle, meiosis, classical and human genetics, genetic disorders and DNA technology, evolution, and then a long run of human anatomy and physiology system by system. In the official 2025 sample, human anatomy, physiology, development and nutrition was the single heaviest area, followed by genetics and the cell cycle.
Chemistry
50%The official syllabus splits into Part I General Chemistry (sixteen headings) and Part II Organic Chemistry and Biochemistry (twenty-three), covering atomic structure through bonding, states of matter, solutions, stoichiometry, kinetics, acids and bases, redox, then the full organic sequence and the biomolecules. Calculation items are frequent in the sample and every one of them has to be solvable without a calculator.
Marks
Charles University LF3 Entrance Exam scoring
Two things about LF3's scoring are published and one is not, and it is worth being precise about which is which. Published: every question is worth one point, and the written part scores from 0 to 60. Not published: whether a wrong answer carries a penalty. LF3 has never stated a marking rule for incorrect answers in any document IvyTest has been able to read, so what follows is flagged rather than asserted.
- Correct answer
- +1 point
- Written part score range
- 0 to 60 points (stated by LF3)
- Incorrect answer
- Not explicitly published. A stated floor of exactly 0, rather than a negative figure, across 60 one-point questions is what a no-penalty scheme produces, and a negative-marking scheme would need a floor rule LF3 has never issued. IvyTest assesses 0 points for a wrong answer as likely, not confirmed.
- Unanswered question
- Not explicitly published; assessed as 0 points on the same reasoning as an incorrect answer
- Answer format
- Single best answer: exactly one of the four options is correct, confirmed across all 60 items of the official 2025 sample
- Minimum eligible score
- No fixed value exists: LF3 states the Dean sets the minimum points to proceed to the second part on the basis of that year's first-part results
- Per-subject floors
- None. LF3 publishes no per-section minimum, and there is no Czech equivalent of the Italian per-subject OFA floors
- Interview (second part)
- 12 to 62 points, scored separately from the written test
- How the two parts combine
- Not published: LF3 describes the written test as the gate to the second part and the interview as separately scored, but states no rule for combining them into a final ranking
Worked example
The IvyTest simulator scores every practice paper against these exact rules.

Charles University Third Faculty entrance exam syllabus (LF3)
Both subjects have an official LF3 premedical syllabus and the content below is the syllabus's own; only the grouping into readable blocks is IvyTest's. One note on the source: the syllabus PDF's filename contains the word 'physics', but the document body and LF3's admissions page both describe the written test as Biology and Chemistry only, so no Physics section appears here.

How difficult is the Charles University LF3 Entrance Exam?
The content of LF3's written test is ordinary school biology and chemistry at Czech grammar-school level. What makes the exam awkward to prepare for is how much about it is unstated, and how much of the admission decision sits outside the paper entirely.
There is no published time limit
IvyTest read LF3's official admissions page in full on 21 September 2026 and it states no duration (not per section, not overall), and a 'three hours' figure circulating elsewhere could not be corroborated in either PDF linked from the faculty's own pages. You therefore cannot derive a per-question pace from official material, which is a real preparation problem: the only sensible response is to practise the same 60-question paper at more than one pace rather than train a single rhythm that may not match the day.
The pass mark is generated after you sit the paper
LF3 states that the Dean sets the minimum number of points needed to proceed to the second part on the basis of that year's first-part results. That is not an unpublished number; it is a number that does not exist in advance. The threshold is whatever that cohort produces, so a score that comfortably qualified one year can fall short the next on an identical paper.
Everything is plain text, including the chemistry
The official 2025 sample test contains no figures at all (no diagrams, no graphs, no reaction schemes), and even organic structures are written inline as text, in the form CH3-CH2-NH-CH3 or HOOC-CH(NH2)-CH2-SH. Anatomical and structural questions are posed in words too. Reading a molecule off a line of characters, quickly and without sketching it, is a specific skill this paper demands and most textbook practice never builds.
Chemistry calculations, by hand, at a third of the block
Calculation items are frequent in the official sample and every one of them has to be solvable without a calculator: molarity, dilution, mass of solute for a given volume, unit conversions between micromoles, millimoles and moles per litre, pH, and balancing redox equations. Acids, bases, pH, redox, kinetics and calculations together made up roughly a third of the sample's chemistry questions.
Half the assessment is not on the paper
The written test is a gate; the second part is a separately scored interview worth 12 to 62 points, assessing interpretation of a popular-scientific text, general overview, independent judgement, communication skills, motivation and an evaluator recommendation. Almost none of that is examined by 60 biology and chemistry multiple-choice questions, and LF3 does not publish how the two scores combine into a final ranking.
Benchmarks
What is a good Charles University LF3 Entrance Exam score?
LF3 publishes no cutoff, and on a full re-read of its official admissions page on 21 September 2026 it explains exactly why: the Dean sets the minimum number of points to proceed to the second part on the basis of the results of the first part. The number is cohort-relative and retrospective by design.
This makes LF3 different from an exam that simply has not released its threshold yet. There is no figure being withheld. If the faculty invites roughly the top N written scores to interview, the cut settles wherever the Nth-ranked candidate lands, which depends entirely on who else applied that year and how they performed. Any specific pass mark quoted elsewhere is somebody's reconstruction of a past cohort, not a rule you can prepare against.
The more useful signal during preparation is your own trajectory on full 60-question mocks, tracked separately for Biology and Chemistry, since the two are exactly equal in weight and there is no third section to compensate. One further caution when comparing figures found elsewhere: LF3 also publishes a Czech-language document for its Czech-medium programme describing a 90-question Biology, Physics and Chemistry paper with its own Dean-set threshold. That is a different exam from the English-taught 60-question test, and its numbers do not transfer.

- · How many first-part candidates are invited to the interview
- · Whether the written and interview scores are combined in the final ranking, and how
- · How many candidates apply for the 90 places of 2027/28
These specific numbers aren't public yet — an IvyTest simulator score is the closest benchmark you can get today.

How to prepare for the Charles University LF3 Entrance Exam

Two subjects, equal weight, no weak half
Biology and Chemistry in parallel at 30 questions each, with no third section to hide behind.
- Sit a full 60-question diagnostic in week one and score Biology and Chemistry separately. They are worth exactly the same, so whichever is weaker is the one that decides your total.
- Work Biology against LF3's own syllabus order: it runs from living systems and bioenergetics through microbiology, cell and molecular biology, genetics and evolution, and then system by system through human anatomy and physiology, which was the heaviest area in the official 2025 sample.
- Build calculator-free chemistry arithmetic from the first week: molarity and dilution, mass of solute for a given volume, micromole-to-millimole conversions, pH, and balancing redox equations. These recur throughout the sample and none of them may be done with a calculator.
- Practise reading organic structures written inline as text, in the sample's own style (CH3-CH2-NH-CH3 rather than a drawn skeleton), because that is how every structural question is posed.
Repair the weaker subject before polishing the stronger
Balanced coverage, with the official sample's weightings as a guide to emphasis.
- Diagnostic first, then put the larger share of the next four weeks into whichever of the two subjects scores lower: a 60-point paper split evenly has no way to carry an imbalance.
- In Biology, prioritise human anatomy and physiology and then genetics and the cell cycle; in Chemistry, prioritise the acids, bases, pH, redox, kinetics and calculations cluster alongside organic chemistry and functional groups. Those were the heaviest areas of the official 2025 sample.
- One full 60-question mock a week from week two, reviewed the same day, with every miss logged as a content gap, a misread question or an arithmetic slip.
- Because no time limit is published, run your mocks at two different paces (a comfortable one and a deliberately tight one), so neither comes as a surprise.
Full 60-question sittings, plain text throughout
Volume of timed papers in the real format.
- Two full 60-question mocks a week, with no diagrams, no calculator, and organic structures written inline exactly as the official sample writes them.
- Drill the chemistry calculation types by hand until they are automatic rather than derived: concentration, dilution, stoichiometric mass, unit conversion, pH.
- Review each mock against both halves separately. A 44 built from 26 Biology and 18 Chemistry is a very different result from a balanced 22 and 22, and only one of them tells you where to spend the next week.
- Answer every question. If LF3's scheme is the no-penalty one IvyTest assesses as likely, a blind four-option guess is worth +0.25 and a blank is worth 0, but confirm the marking rule with the faculty, since it has never been explicitly published.
Shore up the weaker subject, then prepare the interview
Triage across two equal halves, plus the second part.
- Stop adding new topics. Consolidate the highest-frequency areas in whichever subject your mocks show weaker; with only two subjects, that is where the marks are.
- Spend a session purely on calculator-free chemistry arithmetic; it is the most recoverable category of mark on this paper in a short window.
- Sit at least two full, scored 60-question mocks in the final ten days, then taper.
- Reserve real time for the second part. The interview is worth 12 to 62 points and assesses interpretation of a popular-scientific text, general overview, independent judgement, communication and motivation, none of which the written paper rehearses.

FAQ
Charles University LF3 Entrance Exam frequently asked questions
It's the two-part admission process the Third Faculty of Medicine uses for its English-taught General Medicine programme in Prague. The first part is a 60-question written test: 30 Biology and 30 Chemistry, four options each, one point per question, scored 0 to 60. The second part is a separately scored interview worth 12 to 62 points.
Neither. There is no shared national medical entrance test in the Czech Republic, and Charles University's five medical faculties run structurally different papers. LF3 is the only one of the three Prague faculties that tests just two subjects: the First Faculty runs Biology, Chemistry and General Science across 75 questions, and the Second Faculty runs four sections including Physics and Logic. Preparation built for one does not transfer cleanly to another.
No. The English-taught written test is Biology and Chemistry only. This is worth checking carefully against anything you read elsewhere, because LF3's syllabus PDF has the word 'physics' in its filename while the document body and the admissions page both describe a two-subject test, and because LF3 publishes a separate Czech-language document for its Czech-medium programme that does describe a 90-question paper including Physics. That is a different exam.
LF3 does not say. IvyTest re-read the faculty's official admissions page in full on 7 October 2026, with Charles University's 2027/28 admissions record and the 2025 sample test, and none of them gives a time limit for the written test (the only duration LF3 states is the interview's 10 minutes), and a '3 hours' figure that circulates on third-party sites could not be corroborated in either PDF linked from LF3's own pages. Rather than print a number the university has never published, we leave it unverified, and recommend practising the same 60-question paper at more than one pace.
It is an electronic test taken on the applicant's own laptop or other device, in Prague or at a partner agency's sitting abroad. For 2027/28, Charles University's admissions record adds that sittings abroad may be online, with the first round then run by the testing company Scio on questions the faculty supplies, and the faculty itself running the second round. Practically, that means your equipment is part of your preparation. The expected level of knowledge corresponds to the Czech grammar-school framework.
Each question is worth one point and the written part scores from 0 to 60; that much LF3 states directly. Whether a wrong answer carries a penalty is not stated anywhere. IvyTest assesses a no-penalty scheme as likely rather than confirmed, on the reasoning that a stated floor of exactly 0 across 60 one-point questions is what a no-penalty scheme produces, while a negative-marking scheme would need a floor rule the faculty has never issued. If that assessment is right, a blind four-option guess is worth +0.25 points and there is no reason to leave anything blank, but confirm the rule with the faculty rather than taking it as settled.
There is no fixed pass mark, and this is a design choice rather than an omission. LF3 states that the Dean sets the minimum number of points needed to proceed to the second part on the basis of that year's first-part results, and the points required for admission according to the expected number of admissions, so the threshold is produced by the cohort after the exam, not published before it. There are also no per-subject floors; LF3 has no equivalent of the per-subject minimums used by some Italian medical schools.
An interview scored from 12 to 62 points, covering interpretation of a popular-scientific text, general overview, independent judgement, communication skills, motivation and an evaluator recommendation. It lasts 10 minutes in all: five criteria in a text round and six in an interview round, each scored 1 to 5, plus each evaluator's recommendation scored 1 to 7. It is scored separately from the written test. LF3 does not publish how the two scores are combined in the final ranking, so we leave that unverified rather than assuming they are summed.
None at all. The official 2025 sample test contains no figures: every item, including anatomical and structural questions, is posed as plain text, and organic structures are written inline in the form CH3-CH2-NH-CH3 or HOOC-CH(NH2)-CH2-SH. Practising from diagram-heavy material leaves that specific reading skill untrained.
LF3 expects to admit 90 students for 2027/28, as for 2026/27. Charles University's 2027/28 admissions record reports that 92 of 548 applicants were admitted in the past academic year, an acceptance rate of about 17%; the 2026/27 record gave 90 of 436, about 21%. Up to 25 places can go to applicants admitted without the exam, and the threshold to reach the interview is set from that year's results, which makes the competition explicitly relative to the cohort.
Within the EU, yes: automatically, as a standard Czech medical degree. There is no separate national licensing exam afterwards: the Czech state exam is built into the MUDr degree itself, and registration with the Czech Medical Chamber (ČLK) is compulsory to practise in the country. Outside the EU recognition isn't automatic as a rule, but the UK is an exception. Under the Medical Act 1983 (section 21B, as in force on 12 October 2026), a Czech medical degree (MUDr.) is a 'relevant European qualification', so a graduate who applies to the GMC with one, whatever their nationality, is not asked to show the knowledge and skills other international graduates prove through PLAB/UKMLA; evidence of English is still required, and the rule is UK policy that can change. US-bound graduates need ECFMG certification via USMLE Step 1 and Step 2 CK, the same requirement every international medical graduate faces.
Yes. The IvyTest simulator runs LF3-format practice (60 questions, 30 Biology and 30 Chemistry, four options with one correct answer, in the plain-text style of the official sample) in timed, tutor and review modes, with a free diagnostic available without payment.
LF3 publishes no archive of past papers, but its Entrance exam page links three free PDFs: the premedical syllabus for Chemistry and Biology, last year's sample test (the 2025 paper: 30 Biology and 30 Chemistry questions, four options each) and its key, a one-page scanned answer grid. Its Prospects and documents page also points to the premedical course's study materials, lecture handouts from 2016.
Charles University's admissions record for 2027/28 sets the application deadline at 30 April 2027, also the day by which a request to waive the exam must be posted. The written test is in Prague on 28 May 2027, with an alternative date on 1 July 2027, and sittings abroad, some possibly online, run from February to July 2027. Applications open on 1 November 2026, according to LF3's How to apply page; the interview dates are not yet published.
Secondary education completed with a school-leaving examination, an online application with its fee (CZK 2,000 for 2027/28), and the entrance exam unless you qualify for the waiver: A-levels of A, A, B in English, Chemistry and Biology, 19 points in Higher Level IB Chemistry, Biology and English, or similar results taken in 2025/26 or later. Once admitted you post an authenticated, translated school-leaving certificate, a transcript and a passport copy, and pay CZK 990 for its recognition. No English certificate is asked of first-year applicants.
Tuition is CZK 440,000 a year (about €18,000) for students starting in 2027/28, according to Charles University's admissions record and LF3's own pages; it was CZK 420,000 for 2026/27. It is due by 30 October, and students in a difficult financial situation can ask to pay in instalments. The application fee is CZK 2,000 for 2027/28 and the recognition of a foreign school certificate CZK 1,050. LF3 publishes no living-cost estimate; its optional Premedical Course costs CZK 125,000.
Six years, taught in English since 1991/92 alongside the Czech programme and leading to the MUDr. (M.D.) degree. LF3's integrated curriculum runs in three cycles: basic biomedical sciences in years 1 and 2, principles of clinical medicine in years 3 and 4, and clinical preparation in years 5 and 6, with an emphasis on preventive care. Students must be able to use Czech by the end of year 2. The main clinical base is the University Hospital Královské Vinohrady in Prague 10.
LF3 traces its roots to the medical faculty founded with Charles University in 1348; it became the Faculty of Hygiene in 1953 and the Third Faculty of Medicine in 1990. It calls its integrated curriculum the only such reform at a medical school in Central and Eastern Europe, and is accredited by the U.S. Department of Education for U.S. students. LF3's pages cite no world ranking; Charles University's preparatory institute cites the QS World University Rankings 2025 (top 250) and 151-200 in QS Medicine and ShanghaiRanking's Clinical Medicine, for the whole university.
IvyTest publishes no student reviews of its own. LF3's Students and graduates to applicants page carries accounts from four graduates, three of them now in residencies in the USA and Sweden, describing a demanding programme with problem-based learning, and one mentions the language barrier on clinical placements. Its students' association TRIMED has a podcast for applicants, and LF3 offers visits guided by a current student (its Open Day page last listed 9 January 2026).
The content is school Biology and Chemistry at Czech grammar-school level, 30 questions each with one correct answer and every item posed in plain text. What makes it hard is the competition: about 17% of applicants were admitted in the past academic year, the threshold to reach the interview is set from that year's results, and there is no third section to make up for a weak subject.
