About this exam

NSZ Biology (Národní srovnávací zkoušky – Biologie) is a standardized multiple-choice subject test developed by Scio, a Czech education company that has been building tests for roughly three decades. Universities and faculties in Czechia and Slovakia may use NSZ results as one component of their admissions process; whether and how a given faculty weights the Biology test is decided by that faculty, not by Scio, so always check the specific admissions rules of the programme you are applying to. The exam is intended for secondary-school graduates and others preparing for university entrance in biologically oriented fields such as medicine, veterinary medicine, pharmacy, natural sciences, agriculture, and teacher training. Content spans general biology, cell biology, genetics, human biology and anatomy, plant and animal biology, ecology and environment, and evolutionary biology, with an emphasis on conceptual understanding, terminology, and the ability to interpret data and reason from evidence rather than on isolated memorization. Preparation works best as a staged process: build a complete syllabus map first, then work domain by domain using a good secondary-school textbook, and finish with timed practice under exam conditions, reviewing every wrong answer to identify whether the gap was factual, terminological, or a misread question. Scio publishes sample tests and offers preparation materials and practice sittings; these are the most reliable way to calibrate yourself to the actual style and difficulty.

What you'll study

Common questions

About Scio NSZ Biology preparation

What is the format of the NSZ Biology exam?

It is a standardized multiple-choice test delivered by Scio, taken under supervised conditions at announced dates and venues. Questions are in Czech (Slovak and English language options exist for the NSZ system overall). The test is designed for machine scoring, so answers are recorded on an answer sheet or in the testing system rather than written out.

How long is the test and how many questions are there?

Scio publishes the current specification, including item count and time limit, in its official test information and sample materials. Because these parameters are revised between seasons, confirm them on the official Scio pages before you plan your pacing. Do not rely on figures quoted in older forums or prep blogs.

Is there a pass or fail score?

NSZ results are reported as a percentile, comparing you with other test-takers, rather than as a simple pass/fail. Each faculty then sets its own requirement or weighting, so the score you need depends entirely on the programme. Check the admissions conditions of the faculty you are applying to.

Can I retake the exam?

Scio normally offers several exam dates within a season, and candidates may register for more than one sitting subject to the rules and fees published for that season. The best result is typically the one you can use in your application. Confirm the current retake and registration conditions directly with Scio.

How difficult is it compared with school biology?

It is broader than a school leaving exam and rewards precise terminology plus the ability to apply concepts to unfamiliar data. Most candidates find genetics and human physiology the hardest domains because they combine recall with reasoning. Expect questions that require choosing the single best answer among several plausible ones.

What should I study first?

Start with general biology and cell biology, since genetics, physiology, and ecology all build on them. Then move to genetics, human biology, and plant and animal biology, and finish with ecology and evolution, which are smaller shares and easier to consolidate late. Keep a running list of terms you cannot define precisely.

What are the most common mistakes candidates make?

Three recurrences: memorizing lists without understanding mechanisms, ignoring the smaller domains such as ecology and evolution, and never practising under time pressure. A fourth is misreading negatively worded items. Review every practice error and label it as a knowledge gap, a terminology gap, or a careless error.

How should I use practice tests?

Take one full practice test early to establish a baseline, then study by domain, then take further tests strictly timed. After each, spend more time analysing errors than taking the test. Track accuracy per domain so your remaining study time goes where it changes your score most.

Does taking the NSZ Biology guarantee admission?

No. NSZ is one input that faculties may choose to use alongside other criteria such as school results, subject-specific tests, or interviews. Whether the Biology test is required, optional, or weighted heavily varies by faculty and programme, and can change between admissions cycles.

Where do I register and find official dates?

Registration, dates, venues, fees, and sample tests are published on Scio's official website. The current season's first practice sitting and first regular date are announced there. Always treat the official site as the authoritative source, since dates and conditions are updated each cycle.
