About the DZI Biology and Health Education Exam
Държавен зрелостен изпит по биология и здравно образование is Bulgaria's state matriculation examination in biology and health education, administered by the Ministry of Education and Science (МОН). It is a written, anonymous Bulgarian-language test of 4 astronomical hours, scored 0–100 points and converted to 2.00–6.00 under Ordinance No. 11 (passing Fair/Среден 3.00 at 30/100). Students sit two compulsory DZI — Bulgarian Language and Literature plus one chosen subject — and may add optional papers. Biology is offered as ООП or ПП (four modules: cell; multicellular organisation; biosphere; evolution). The official paper mixes closed and open tasks. This free English MCQ bank is a study adaptation of curriculum content — not an official translation, format simulation, or substitute for the Bulgarian written DZI.
Assessment
Official ДЗИ по биология и здравно образование is a written, anonymous Bulgarian-language test lasting 4 astronomical hours, typically in two parts (about 90 then 150 minutes). Papers exist for общообразователна подготовка (ООП) and профилирана подготовка (ПП: four compulsory modules — Клетката; Многоклетъчна организация; Биосфера; Еволюция). Tasks mix closed items with short and extended constructed responses, scored to a 100-point maximum. This 100-question bank is an English MCQ study adaptation only — it does not simulate the official mixed-format paper or substitute for Bulgarian written practice.

Frequently Asked Questions
Is the official DZI Biology exam a multiple-choice test in English?
No. The official ДЗИ по биология и здравно образование is a written, anonymous paper in Bulgarian that mixes closed items with short and extended constructed-response tasks. This bank is an English-language MCQ study adaptation — not an official translation, format simulation, or substitute for the real exam.
How long is the DZI Biology exam and when is the 2026 sitting?
Duration is 4 astronomical hours (240 minutes), typically split into two parts. In the May 2026 session the second compulsory DZI — the slot used when biology is the chosen subject — is on 22 May 2026 at 08:30.
What score is needed to pass?
Papers are scored 0–100 points and converted to 2.00–6.00 under Ordinance No. 11 of 1 September 2016. Passing is Fair/Среден 3.00. MON's unified DZI scale sets Среден at 30% of maximum points (30/100).
What is the difference between ООП and ПП biology papers?
ООП (общообразователна подготовка) assesses first-gymnasium biology (about grades 8–10). ПП (профилирана подготовка) assesses the four compulsory profiling modules in grades 11–12: Клетката; Многоклетъчна организация на биологичните системи; Биосфера – структура и процеси; Еволюция на биологичните системи. Choose the paper that matches how you studied the subject.
Is biology one of the two compulsory DZI?
Every candidate must sit Bulgarian Language and Literature plus one chosen subject. Biology can be that second compulsory paper if selected, or an optional additional DZI. Eurydice notes that both compulsory exams must be passed for a diploma giving access to higher education.
Is there a published exam fee for Grade 12 school candidates?
No separately published national candidate tariff applies to current Grade 12 public-school students sitting DZI through their school. Do not rely on unofficial euro figures. External or competence-validation sittings follow MON/school procedures.
What official documents should I use besides this practice bank?
Use the MON DZI pages, the subject изпитни материали for биология и здравно образование, the УИП sample tasks, Ordinance No. 11, and the published ДЗИ scoring scale. Past session papers are released on the MON site after each sitting.
