Typical topics include-

• Logical reasoning
• Numerical ability
• Data interpretation
• Quantitative analysis

Part B- Subject Knowledge

Part B moves into your chosen subject. Here, the exam tests your core concepts and fundamental understanding of the discipline you selected while applying.

You can expect-

• Concept-based questions
• Subject fundamentals
• Moderate difficulty level questions

Part C- Advanced Analytical Questions

Part C presents the most challenging section of the paper. Instead of testing memorisation, it focuses on analytical and application-based problem solving.

Questions typically require you to-

• Apply concepts to complex problems
• Analyse scientific scenarios
• Demonstrate research aptitude
