4. Create a Timetable for Study

During your GATE preparation schedule, aim to set weekly and daily goals to track your progress. Each Subject should be divided so that they do not get repetitive, and extra time should be spent on those subjects where you find difficulty in learning. It is essential to revise this helps you learn topics for long-term retention. Finally gives mock tests that help you to track your daily progress.

5. Choose the Proper Study Material

Excellent online courses such as the GATE CS-IT 2025 Course are developed and delivered by experienced educators and subject-matter experts. This means students can benefit from the expertise and knowledge of educators who understand the delicacy of GATE.

6. Solve PYQs

Make sure that you have solved all the previous year's gate questions for individual subjects after completing it. This will help you to get an idea of how questions are structured in gate exams and also solve a variety of questions.

7. Do not Leave Aptitude and Engineering Maths

This is a very common mistake made by students, they leave aptitude and engineering mathematics which are very easy and high-scoring subjects. So make sure not to leave these subjects.

8. Syllabus Completion

Complete your syllabus at the end of October or before the beginning of November this will give you fully sufficient time for revision and mock tests.

How to Get AIR Under 100?
