Questions students ask
65 questions, all compulsory: 10 in General Aptitude and 55 in Biotechnology.
The paper is 100 marks in 3 hours.
In MCQs, a wrong answer loses 1/3 mark (1-mark questions) or 2/3 mark (2-mark questions). MSQ and NAT questions have no negative marking.
All 10 papers here follow this pattern.
Across these 10 papers, the Biotechnology section asked Bioprocess & Bioengineering the most (94 questions), then Mathematics (81), Biochemistry (54), Microbiology (49) and RDT & Tissue Culture (48). Engineering and Maths carry more weight here than in most Life Sciences exams.
Yes. Every question and option is from the official paper, retyped by our team so every question is clean and easy to read. Every answer is checked against the official final answer key, and where a question was dropped or its answer changed, the PDF says so.
