GAT B Section A Exam Pattern and Marks Distribution 2026
GAT B has two sections. Mathematics appears only in Section A, at Class 12 NCERT level.
| Section | Questions | Level | Correct | Wrong |
|---|---|---|---|---|
| Section A | 60 (all compulsory) | Class 12 - Physics, Chemistry, Mathematics, Biology | +1 | -0.5 |
| Section B | 100 (attempt any 60) | Bachelor's level - Life Sciences, Biotechnology | +3 | -1 |
- Mathematics in Section A: approximately 15 out of 60 total questions
- All MCQs: four options, one correct answer
- Duration: 180 minutes, online, conducted by NTA
GAT B Mathematics Papers and NCERT Class 12 Base - Why 2022 to 2025 Papers Matter Most
GAT B Section A Mathematics draws directly from NCERT Class 12. Papers from 2022 to 2025 show the same pattern: Calculus takes the largest share of Mathematics questions each year, followed by Probability and Statistics.
- Start with the 2024 paper - it reflects the current question format and difficulty most accurately.
- Skip papers before 2021. The Mathematics question distribution shifted after 2020.
- Probability and Statistics questions are worth double attention: they appear in Section A Mathematics and also underpin biostatistics concepts in Section B.
GAT B Mathematics Chapter Wise Weightage - High Scoring Topics to Focus in Sample Papers
Based on 2021 to 2025 paper analysis, here is the topic distribution for Mathematics in Section A.
| Chapter | Questions (approx) | Difficulty | What to Watch For |
|---|---|---|---|
| Calculus - Limits and Continuity | 2-3 | Moderate | Standard limits, L'Hopital rule |
| Calculus - Differentiation | 2-3 | Moderate | Chain rule, implicit differentiation |
| Calculus - Integration | 2-3 | Moderate-Hard | Definite integrals, substitution, area under curve |
| Probability and Statistics | 2-3 | Easy-Moderate | Bayes theorem, conditional probability, variance |
| Matrices and Determinants | 1-2 | Easy | Inverse matrix, determinant properties |
| Vectors | 1-2 | Easy-Moderate | Dot and cross product, angle between vectors |
| 3D Geometry | 1-2 | Moderate | Direction cosines, lines and planes |
| Relations and Functions | 1-2 | Easy | One-one, onto, composition of functions |
| Linear Programming | 0-1 | Easy | Feasible region, corner point method |
| Trigonometry | 0-1 | Easy | Inverse trig identities, principal values |
Do not skip Relations and Functions or Trigonometry. These carry 1 to 2 questions each but are among the fastest to solve - they require recall, not calculation.

How to Use GAT B Mathematics Sample Papers to Clear Section A in First Attempt
- First paper untimed: Solve without a clock. Log every wrong answer with the chapter name and mistake type - concept gap or calculation error.
- Fix concept gaps in NCERT: Go back to the source chapter before attempting the next paper. More papers without concept fixes do not improve accuracy.
- Second paper with a 30-minute timer: The Mathematics portion of Section A should take no more than 30 minutes in the actual exam.
- Watch negative marking: If you mark more than 3 wrong answers per paper, you are guessing too often. Flag uncertain questions and move on.
GAT B Mathematics NCERT vs PYQ Balance - How to Use Sample Papers Without Wasting Time
NCERT is the base; PYQs show which concepts NTA picks. Use both together.
- After each paper, trace every wrong Mathematics answer to its NCERT source - the theorem, example, or exercise it came from.
- Calculus questions in GAT B PYQs are almost always direct adaptations of NCERT worked examples.
- Do not use books beyond NCERT and RD Sharma for Section A Mathematics. The questions stay within Class 12 standard.
GAT B Mathematics 4 Week Preparation Plan Using Sample Papers
- Week 1 - Solve the 2024 full paper untimed. Identify the three Mathematics chapters with the most wrong answers.
- Week 2 - Revise those three chapters from NCERT, then solve 2023 with a 30-minute timer for the Mathematics section.
- Week 3 - Solve 2022 and 2021 papers back to back under exam timing. Track Mathematics accuracy and wrong-answer count across both.
- Week 4 - One full sample paper daily. Stop new papers two days before the exam; review your error log only.
FAQs on GAT B Mathematics Sample Papers 2026
Ques. How many GAT B Mathematics sample papers are enough to score well in Section A?
Ans. Five to seven papers with a consistent error log. Reviewing mistakes after each paper matters more than volume.
Ques. Are GAT B Mathematics questions repeated across years?
Ans. Exact questions are not repeated, but Calculus and Probability appear every year with near-identical frequency across 2021 to 2025 papers.
Ques. Which year GAT B paper should I start with for Mathematics practice?
Ans. Start with 2024 - it is the closest to the current pattern and gives the clearest baseline.
Ques. Can I score full marks in GAT B Mathematics in 30 days?
Ans. Yes. All Section A Mathematics questions are NCERT Class 12 standard. Four weeks of targeted practice plus five sample papers is enough for most students.
Ques. Where can I download GAT B Mathematics sample papers with answer key PDF for free?
Ans. Download the numbered sample papers above. For previous year papers with solutions, check the Collegedunia GAT B question paper page and the official NTA website dbt.nta.ac.in.
Ques. Is NCERT Class 12 enough for GAT B Mathematics Section A?
Ans. Yes. NCERT Class 12 covers all GAT B Section A Mathematics. Add RD Sharma for extra Calculus practice if needed.
