To take GATE mock tests, first choose a reliable source like GATE official portal, NPTEL, Made Easy, or ACE Engineering. Sign up or register online to access the full-length tests. Simulate the actual 3-hour exam with proper timing and no distractions. Attempt complete tests to practice time management and exam strategy. After each test, analyze your performance to identify weak areas and revise. Regularly taking 1–2 mocks per week helps improve speed, accuracy, and confidence.



For GATE Life Sciences question banks, you can go for GATE past year's papers to understand the exam style, and you can buy online test series from a coaching site for lots of new practice questions.

you can get question book one from publishers like IFAS or GKP. Also use free online resources like NPTEL and EasyBiologyClass for extra practice and study materials. Good luck!

Here are GATE exam aptitude topics from high to low weightage:

1. English Comprehension & Vocabulary

2.Numerical Ability and Arithmetic

3.Logical Reasoning & Analytical Ability

4.Data Interpretation

5.Geometry & Mensuration basic

6.Algebra basic
