GAT-B 2026 Exam Overview

Key Highlights

Let’s start with some key pointers about the GAT-B 2026 exam:

These details form the core of your exam strategy. Knowing the format inside-out helps in reducing surprises on exam day.

Exam Pattern and Structure

The GAT-B exam is split into two main sections:

Part A – General Aptitude

This section consists of 60 MCQs based on General Science, Mathematics, Analytical Ability, and Comprehension. Each correct answer earns you one mark, while every incorrect response deducts 0.5 marks.

This part is meant to evaluate your basic scientific understanding and problem-solving skills. Though it may seem generic, it is incredibly crucial. Many students ignore this part and end up losing easy marks.

Part B – Subject-Specific Questions

This is where the real action happens. Part B has 100 questions, each carrying three marks. These are purely from your Biotechnology syllabus and related domains like Molecular Biology, Cell Biology, Genetics, Biochemistry, and more.

What’s interesting? There is no negative marking in Part B, which means you can take a few educated guesses without fear.

Important Dates to Remember

Although the official schedule for GAT-B 2026 is yet to be released, here’s a tentative timeline based on previous years:

Keeping these dates in your planner is vital to avoid missing any crucial steps. Remember, late preparation = lost opportunity.

Eligibility Criteria for GAT-B 2026

Academic Qualifications

To be eligible for GAT-B 2026, candidates must fulfill the following academic requirements:

• Must have completed or be in the final year of a Bachelor’s degree in Biotechnology or allied fields, such as Life Sciences, Microbiology, Genetics, Molecular Biology, Biochemistry, etc.
• Candidates must have secured at least 60% aggregate marks (or equivalent CGPA). For reserved categories like SC/ST/PwD, 55% is acceptable.

It’s important to check the specific requirements of the institute you’re applying to, as some of them may have additional criteria like specific subjects or minimum grades.

Age Limit and Attempts

One of the great things about GAT-B is that there is no upper age limit for candidates appearing in the exam. This makes it highly accessible to all students, regardless of age or academic gap.

Also, there is no restriction on the number of attempts. So, even if you don’t succeed on your first try, you can always come back stronger next year.

Preparation Strategy for GAT-B 2026

How to Start Your Preparation

The first thing to do when starting your GAT-B prep is to understand the exam pattern and syllabus completely. Print it out. Stick it on your wall. Then, begin with a simple breakdown of each topic and sub-topic.

Create a study calendar with Chandu Biology Classes’ official time-table or use their monthly preparation plan if you’re enrolled in their courses. Make sure you devote at least 3 hours daily, with weekends reserved for revision and mock tests.

Here’s how your weekly routine should look like:

• Monday to Friday: 2 hours topic-wise study + 1 hour previous year paper practice
• Saturday: Full-length mock test
• Sunday: Doubt-clearing + revision

Don’t skip general aptitude. Even though it’s only 60 marks, these are often the easiest to score. Use logical reasoning books and practice from Chandu’s curated aptitude worksheets.

Common Mistakes to Avoid

Let’s face it—many students fail not because they aren’t smart, but because they fall into common preparation traps:

• Ignoring General Aptitude: As mentioned earlier, this can cost you easy marks.
• Overstudying Without Revision: Reading 10 books won’t help unless you revise regularly.
• No Mock Test Practice: If you’re not testing yourself under exam conditions, you’re not truly preparing.
• Memorizing Without Understanding: This will backfire when tricky application-based questions show up.

Chandu Biology Classes helps you avoid all of this with structured preparation, focused revision, and constant testing. Their adaptive learning system even analyzes your weak areas and adjusts lesson plans accordingly.

Mock Tests and Practice Papers

Why Mock Tests Matter

Mock tests are not just practice—they’re a simulation. The GAT-B exam is time-bound, and your brain needs to get used to that pressure. Taking regular mock tests helps in:

• Improving Speed and Accuracy
