GAT-B 2026 Exam Pattern
GAT-B is conducted in computer-based test mode. The question paper has two parts: Part A and Part B. Part A includes Class 12-level questions from Physics, Chemistry, Mathematics and Biology. Part B includes Bachelor’s-level questions from Basic Biology, Life Sciences, Biotechnology and allied areas. Collegedunia’s exam pattern page also confirms the 160-question structure, 120 attempted questions and 240 total marks.
| Section | Question Level | Total Questions | Questions to Attempt | Marks |
|---|---|---|---|---|
| Part A | 10+2 level: Physics, Chemistry, Mathematics, Biology | 60 | 60 | 60 |
| Part B | Bachelor’s level: Basic Biology, Life Sciences, Biotechnology and allied areas | 100 | 60 | 180 |
| Total | 160 | 120 | 240 |
For detailed syllabus, students can check GAT-B Syllabus.
GAT-B 2026 Marking Scheme
GAT-B has negative marking in both sections. So, students should calculate both correct and incorrect answers carefully.
| Section | Marks for Correct Answer | Marks Deducted for Wrong Answer | Marks for Unattempted Question |
|---|---|---|---|
| Part A | +1 | -0.5 | 0 |
| Part B | +3 | -1 | 0 |
There is no mark deduction for unattempted questions.
GAT-B Score Calculation Formula 2026
The GAT-B score is calculated separately for Part A and Part B. Then both section scores are added to get the final expected score.
Part A Score Formula
Part A Score = Correct Answers × 1 - Wrong Answers × 0.5
Part B Score Formula
Part B Score = Correct Answers × 3 - Wrong Answers × 1
Total GAT-B Score Formula
Total GAT-B Score = Part A Score + Part B Score
The final score is calculated out of 240 marks.
Example of GAT-B Score Calculation
Suppose a candidate has the following responses:
| Section | Correct Answers | Wrong Answers | Score Calculation | Score |
|---|---|---|---|---|
| Part A | 42 | 12 | 42 × 1 - 12 × 0.5 | 36 |
| Part B | 45 | 15 | 45 × 3 - 15 × 1 | 120 |
| Total | 87 | 27 | Part A + Part B | 156 out of 240 |
In this case, the expected GAT-B score will be 156 out of 240.
Students should recalculate their marks after the final answer key is released because the score may change if NTA revises any answer.
GAT-B Response Sheet Score Calculator: Why It Is Useful?
The GAT-B response sheet score calculator helps students avoid manual calculation errors. Since GAT-B has different marks and negative marking for Part A and Part B, manual score calculation can be confusing.
Key Benefits
- Calculates expected GAT-B marks out of 240
- Applies Part A and Part B marking rules separately
- Helps avoid negative-marking mistakes
- Uses answer key and recorded response data
- Helps estimate result chances before official scorecard
- Helps compare score with previous-year GAT-B cutoff
- Useful for admission planning before counselling or institute-level process
Students should use the latest answer key for the most accurate score estimate.
How to Download GAT-B Answer Key and Response Sheet 2026?
Candidates can download the GAT-B answer key, question paper and recorded responses from the official NTA login.
Steps to Download GAT-B 2026 Answer Key

Candidates who find any error in the provisional key can raise objections before the deadline. NTA has stated that challenges submitted without fee payment or through any mode other than the official online portal will not be accepted.
GAT-B Answer Key 2026: What to Check Before Calculating Score?
Before using the score calculator, check the following details carefully:
| Checkpoint | Why It Matters |
|---|---|
| Correct response sheet | Make sure the response sheet belongs to your application |
| Latest answer key | Use the provisional or final key available at that time |
| Section-wise responses | Part A and Part B have different marking rules |
| Wrong answers | Negative marking applies in both sections |
| Unattempted questions | No marks are added or deducted |
| Revised answers | Final score may change after objections |
Use the final answer key for the most accurate score estimate.
GAT-B Final Answer Key 2026
The GAT-B final answer key will be released after NTA reviews the objections submitted against the provisional key. If a challenge is accepted, the answer key will be revised and applied to all candidates.
The final answer key is important because:
- It is used for result preparation.
- It may include revised answers.
- It gives a more accurate score estimate.
- It helps students compare scores with cutoff.
- It reduces mismatch between predicted score and official scorecard.
Students should not rely only on the provisional-key score once the final answer key is released.
What is a Good Score in GAT-B 2026?
A good score in GAT-B depends on the difficulty level, number of candidates, category, institute preference and seat availability. The table below gives a broad expected score range.
| GAT-B Score out of 240 | Performance Level | Admission Outlook |
|---|---|---|
| 190+ | Excellent | Strong chance for top DBT-supported institutes |
| 170 - 189 | Very Good | Good chance for popular programmes and institutes |
| 150 - 169 | Good | Decent admission chances depending on category and seats |
| 130 - 149 | Moderate | Chances depend on cutoff and institute preference |
| 110 - 129 | Average | Limited chances in high-demand institutes |
| Below 110 | Low to Moderate | Admission depends on category, cutoff and vacant seats |
This table is only for reference. Students should compare their score with GAT-B Cutoff after the result.
GAT-B Score vs Cutoff 2026
GAT-B cutoff is the minimum score or percentile required for further admission process. The cutoff changes every year based on exam difficulty, number of test-takers, seat availability and category.
| Factor | Impact on Cutoff |
|---|---|
| Paper difficulty | Tough paper may lower cutoff |
| Number of candidates | More candidates can increase competition |
| Available seats | Fewer seats may increase cutoff |
| Category | Cutoff differs for General, OBC, SC, ST, EWS and PwD |
| Institute preference | Popular institutes may have higher cutoff |
Collegedunia’s GAT-B page notes previous-year category-wise cutoff percentile references, including General, SC and ST category values from past data. Students should wait for the official 2026 cutoff for final admission decisions.
GAT-B Score Calculator vs Result vs Cutoff
Students often confuse score calculator, result and cutoff. These are connected but different.
| Tool / Update | What It Does | When to Use |
|---|---|---|
| GAT-B Score Calculator | Calculates expected marks from answer key and response sheet | After answer key release |
| GAT-B Result | Shows official score and qualifying status | After NTA result declaration |
| GAT-B Cutoff | Shows minimum marks or percentile needed for admission process | After result / admission process |
| GAT-B Participating Colleges | Helps check institutes accepting GAT-B score | During admission planning |
| GAT-B Syllabus | Helps understand Part A and Part B topics | During preparation or score analysis |
Students should first calculate their expected marks, then check result, cutoff and participating institutes.
