How to Take a Full-Length Mock Test
- Set aside an uninterrupted three-hour session and keep only the permitted practice materials nearby.
- Start with your preferred section, keeping track of the maximum attempts in Parts A, B and C.
- Read analytical questions carefully and avoid spending too long on a single problem.
- Use the question navigation and review features within the test to revisit uncertain answers.
- Submit within 180 minutes, review the explanations and identify weak concepts for revision.
What Do Parts A, B and C Assess?
| Section | Primary focus |
|---|---|
| Part A | General Science, quantitative reasoning, logical and graphical analysis, and research aptitude. |
| Part B | Subject knowledge drawn from the Life Sciences and Biotechnology syllabus. |
| Part C | Application of scientific concepts, interpretation of experimental results, numerical reasoning and multi-step analysis. |
Frequently Asked Questions
How many full-length mock tests are available?
Four full-length papers cover the revised 14-unit Life Sciences and Biotechnology syllabus, with a separate General Aptitude section.
How long is each mock test?
Each test lasts 180 minutes (three hours), matching the published examination duration.
How many questions should I attempt?
The published scheme permits up to 15 in Part A, 35 in Part B and 25 in Part C, giving a maximum of 75 attempted questions.
Is there negative marking?
Yes. The published Life Sciences and Biotechnology scheme deducts 25% of the marks assigned to a question for each incorrect answer: 0.5 marks in Parts A and B, and 1 mark in Part C.
Should I take unit-wise tests before full-length mocks?
Unit-wise tests are useful for learning individual topics. Full-length mock tests help practise time allocation and switching between General Aptitude, subject knowledge and analytical problems.
When should I review my answers?
After completing a paper, examine incorrect and unattempted questions, revise the related concepts and track patterns in your errors.
