- Section B and C test conceptual clarity and numerical ability
- The exam is fully online (CBT mode)
IFAS Highlights
Section | Marks per Question | Negative Marking |
|---|---|---|
Section A (MCQ) | 1 or 2 marks | Yes (-1/3 for 1 mark, -2/3 for 2 marks) |
Section B (MSQ) | 2 marks | No |
Section C (NAT) | 1 or 2 marks | No |
Key Points:
- Negative marking applies only in Section A
- No partial marking in MSQ questions
- NAT questions require numerical answers (no options)
- Unattempted questions carry zero marks
- Probability & Random Variables
- Standard Distributions
- Statistical Inference
- Linear Algebra & Matrices
- Calculus (Differential & Integral)
- Sampling & Estimation
These topics are frequently asked and carry significant marks in the exam.
Before starting preparation, clearly understand the paper structure and marking scheme.
2. Focus on Conceptual Clarity
Avoid rote learning—focus on formulas, derivations, and applications.
3. Practice Numerical Problems
Since NAT questions are important, regular problem-solving is essential.
4. Solve Previous Year Papers
PYQs help you understand:
- Question trends
- Difficulty level
- Important topics
5. Time Management Strategy
- Attempt NAT & MSQ first (no negative marking)
- Then solve MCQs carefully
- Plan your study effectively
- Identify strong & weak areas
- Focus on high-weightage topics
- Avoid wasting time on irrelevant topics
