About the BCS Written Zoology Exam
BCS Written Post-Related Zoology (Subject Code 591) is a 200-mark descriptive paper in the Bangladesh Civil Service written stage, used by technical/professional cadre and dual-cadre applicants whose post requires zoology. The official BPSC syllabus splits 100 marks on Animal Biodiversity (major phyla, named genera, life histories, and vertebrate natural history) and 100 marks on General Zoology (cell and gene, evolution, ecology, wildlife of Bangladesh, zoogeography, human physiology and population, embryology, and economic zoology). BPSC does not publish an official MCQ count. This free bank is an English-language MCQ study adaptation of that syllabus—not an official translation, format simulation, or substitute for timed Bangla/English writing practice.
Assessment
Post-related written paper, Subject Code 591, 200 marks in two parts of 100 marks each: Part I Animal Biodiversity and Part II General Zoology (cytology, genetics, evolution, ecology, wildlife, zoogeography, human physiology and population, embryology, economic zoology). Official answers are descriptive. This bank is an English MCQ study aid, not a sitting simulation. Technical/professional cadre candidates take this paper as the 200-mark post-related subject within the 900-mark written stage; dual-cadre applicants sit it in addition to the general-cadre set.

Frequently Asked Questions
What is BCS Written Post-Related Zoology?
It is Subject Code 591 in the BPSC BCS written syllabus: a 200-mark post-related paper (Part I Animal Biodiversity 100 marks, Part II General Zoology 100 marks). Technical/professional cadre and dual-cadre applicants sit it as part of the 900-mark written stage.
Is the official Zoology paper multiple choice?
No. BPSC examines Zoology 591 as a descriptive written paper. This site’s questions are an English-language MCQ study adaptation of the official syllabus, not an official translation, not a past paper, and not a format simulation. You still need timed writing practice.
How long is the paper and what is the pass rule?
This site and longstanding BPSC practice treat 200-mark written papers as 4-hour sittings; confirm the current routine. BPSC’s page requires 50% aggregate on the 900-mark written examination, with per-paper minima as set by the Commission.
Is there a separate fee for the written Zoology paper?
No. The BCS application fee covers the cycle. For the 50th BCS that fee is Tk. 200 general and Tk. 50 for ethnic-minority, disability, and third-gender applicants via Teletalk. Confirm the live circular.
Who sits Zoology instead of the general-cadre written set?
General cadre sits compulsory papers (including 200-mark Bangla). Technical/professional cadre replaces part of that set with a 200-mark post-related subject such as Zoology. Dual-cadre applicants sit the extra post-related paper.
Does this bank use official wildlife census numbers?
No. The BPSC syllabus asks principles of conservation, named protected-area categories, and fauna of Bangladesh, not a particular year’s tiger or elephant census. Questions test those concepts without invented headcounts.
What language is this practice bank?
Official BCS written answers may be offered in Bangla or English as the sitting rules allow. This bank is an original English-language MCQ study adaptation; it is not an official BPSC translation or a claim that the live paper is MCQ-only English.
What comes after the written stage?
Viva voce. The BPSC page still lists viva at 200 marks with a 50% pass. News coverage from the 47th BCS onward has reported a 100-mark viva, and PSC has discussed further change—confirm the current circular rather than assuming either figure.
