Know How to Study
Once you are aware of what to study, it is equally important to know how to study. Managing EE preparation is not difficult if we have a proper study plan. By saying proper study plan, we mean a timetable which we expect you will follow till the end. Your daily study schedule should consist of at least 10-12 hours of quality study time. Don’t overburden yourself, though. One should consider taking breathers and sometimes a power nap to recharge for a more productive preparation.

Manage your Time Efficiently
The lost time is never found again’. As a GATE aspirant, you will relate to it. We understand that there is a lot to study and retain during GATE exam preparation and that is why cracking the GATE and becoming an Electrical Engineer is not everyone’s cup of tea. What differentiates brilliant students from other students is their time management. They smartly manage their time and always keep their goals in mind. It is vital to give yourself time not only for studies, but also for co-curricular activities like physical exercise, meditation, yoga, or socializing with friends and family.
Practice solving Mock Tests and Previous Year Papers
Solving practice papers such as MTPs, RTPs, and PYPs while preparing gives you a tremendous amount of confidence. You get a fair bit of idea about how to present the answers in your exam. Attempting practice papers gives you a reality check so that you can direct your preparation accordingly. The number of practice papers attempted during preparation is directly proportional to getting a good score in the GATE.
Don’t Neglect Revision
It is very important to revise what has been studied. It is a human tendency to forget things with time and the GATE EE syllabus is no exception to it. The syllabus is vast, time-consuming, and complex. So, it is strongly recommended to devote time to your revision. However, revision should not be done in a haphazard manner. Without proper and efficient revision, the entire study effort goes to waste.
Besides implementing these tips, it is your dedication and consistency in GATE preparation that will help you reach closer to your dream score in Electrical Engineering.
