- Practice reading comprehension, grammar, and vocabulary at 10th standard level
- Use any standard 10th Tamil guide or Tamil SSLC question papers
- Target 40/50 (80%+) to be safe, since you only need 40% to qualify
Step 6: MCQ Practice Strategy
- Solve at least 3000-5000 MCQs before the exam
- Use timed practice (100 questions in 90-100 minutes, leaving buffer)
- Focus on clinical reasoning questions - basic science questions are applied
- Review rationales, not just answers
- Sources: MRB PYQs, AIIMS/PGI style MCQ books, NExT mock tests
6. Important Practical Tips

- UG level means: Avoid going too deep into PG-level subspecialty details - stick to MBBS textbook fundamentals
- Normalization applies if the exam has multiple sessions - your raw score may be adjusted
- CBT format: Practice on a computer screen; time management is critical in 2 hours for 100 questions (1.2 min/question)
- Tamil Council registration must be valid and in place before the notification date for the cycle you apply to
