- Move to Part C: Attempt Part C while your mind is still fresh. Select questions carefully – attempt only those you’re confident about.
- Finally, attempt Part A: General aptitude questions are usually straightforward. Leave them for the end when you might be mentally tired from subject-specific questions.
Question Selection
Remember, you don’t need to attempt all questions in Parts B and C. Be strategic:
- Quickly scan all questions in a section before attempting any
- Mark easy and medium questions that you’re confident about
- Attempt these marked questions first
- Return to difficult questions only if time permits
- Never randomly guess in negative marking sections
Time Allocation
Distribute your 180 minutes wisely:
- Part A: 30-35 minutes (all 20 questions are compulsory)
- Part B: 50-60 minutes (select and attempt 25 questions)
- Part C: 70-80 minutes (select and attempt 25 questions)
- Final review: 10-15 minutes
Common Mistakes to Avoid
