Hello Ananya

You should start your preparation from 5 th sem or before it depending upon your college schedule.

And you should not get distracted and focus on study means that attend all the classes and whatever is taufht to you in class ; understand it and don't ignore it like other students do ( they think that we will do it during exam).

Gate required only practice and concepts.

College Life is the most distracting and lazy life but you must be determined and focus and don't waste time .

Make a proper schedule .

First go through the syllabus and than prepare beacause many times students do extra which is the wastage of time and energy.

You should choose good quality books.

Good luck
