About this exam

Kemija (Chemistry) is one of the elective subjects of the Državna matura, the state matura examination that Croatian candidates take at the end of secondary education. A passing grade in Chemistry can serve as a subject requirement for admission to university programmes in chemistry, chemical engineering, pharmacy, medicine, food technology, biotechnology and related fields, and many faculties count it toward admission points. The exam is written externally and is designed for gymnasium graduates and other candidates who have followed the chemistry curriculum, so it rewards solid coverage of the whole syllabus rather than narrow drilling. The assessed content spans the structure of matter and bonding, reaction stoichiometry and energetics, inorganic chemistry and the periodic system, organic chemistry and biochemistry, equilibrium, acids and bases, electrochemistry, and laboratory work with data analysis and calculation. Preparation works best as a staged process: revise each topic from your textbook and notes, then practise calculation types until they are automatic, then work through published exam materials under timed conditions. Because questions combine data, graphs and multi-step reasoning, candidates should rehearse reading tasks carefully and showing working clearly. The National Centre for External Evaluation of Education (NCVVO) publishes the current exam catalogue, subject specification and past papers, and candidates should treat those documents as the authoritative source for format and administrative details.

What you'll study

Common questions

About Državna Matura Chemistry preparation

What is the format of the Chemistry state matura exam?

It is a written, externally assessed examination set by NCVVO. Tasks include multiple-choice items, short-answer questions, structured and extended-response tasks, and calculation or data-interpretation problems based on tables, graphs or experimental descriptions. The official subject catalogue and specification on the NCVVO website give the current task types, weighting and marking rules.

How long is the exam and how many points is it worth?

The official body publishes the current duration, number of tasks and total point value each exam session, and these can change between years. Do not rely on second-hand numbers from forums. Check the current subject specification and exam catalogue on the NCVVO site before planning your timing strategy.

How difficult is Chemistry compared with other electives?

Candidates generally find it demanding because it mixes recall of factual chemistry with numerical calculation and interpretation of unfamiliar data. The calculation load is the main difference from more descriptive subjects. Difficulty feels lower if you have practised stoichiometry, equilibrium and electrochemistry problems until you can set them up without hesitation.

Can I retake the exam if I am unhappy with my grade?

Retake rules, allowed attempts and how results are counted for admission are set by the official regulations and updated periodically. NCVVO and the university admission services publish the current rules. Confirm the position for your enrolment year before deciding, because deadlines for registering a retake fall well before the exam session.

In what order should I study the topics?

Start with structure of matter and bonding, since bonding explains periodicity, inorganic behaviour and organic functional groups. Then build stoichiometry and energetics, because nearly every later calculation depends on them. Add inorganic and organic chemistry systematically, then equilibrium, acids and bases, and electrochemistry, which combine earlier ideas. Finish with mixed data-analysis and laboratory tasks.

What causes most lost points?

Three patterns dominate: unbalanced equations or wrong mole ratios in multi-step calculations, answers that ignore the units or significant figures requested, and vague explanations where the task asks for a chemical reason. Reading the whole task before calculating and stating the final answer with units prevents many avoidable losses.

Do I need to memorise organic reactions?

Yes, but understanding beats listing. You should know functional groups, typical reactions and their conditions, and be able to predict products and name compounds. Examiners often ask you to explain why a reaction occurs or to distinguish similar compounds using a simple test, so link each reaction to structure and to a practical observation.

How should I use past papers?

Use them late in preparation and under timed conditions, then mark strictly against the official answer key. Record every lost point by topic and error type, whether knowledge, calculation or careless reading, and revise that weakness before attempting another paper. Two or three carefully analysed papers teach more than many rushed ones.

Is a calculator allowed, and does it matter?

The official instructions for each session list permitted aids, including the type of calculator and any data booklet. Check the current NCVVO instructions rather than assuming. Practise with the same model you will bring, especially for logarithms, powers of ten and significant figures used in pH and equilibrium calculations.

Does the Chemistry grade guarantee university admission?

No. Admission depends on each faculty's requirements, which may specify Chemistry as a mandatory or optional subject, set minimum grade thresholds and combine the result with other subjects or entrance criteria. Check the current admission conditions published by the university or faculty you are applying to.
