Hello aspirant,

First of all,it depends upon the toughness level of exam and your study regarding the exam

If your target is to score good marks in gate,then you need to be conceptually clear.Firstly, you have to understand the total syllabus and pattern for the exam. you should focus on basic concepts.Also you should be well prepared for aptitude and mathematics to increase your score.

Prepare notes and you can solve the previous years question papers for practice.

It's quite difficult to secure below 50 rank as you are from tough branch,but not impossible.

So study well.

Go for it and give your best shot

Good luck!!!
