Some useful Tips:

1-Study good quality (Totally Exam Oriented).

2-Follow the notes instead of Books (if you don't have make yours).

3-Make short notes(which includes only important Formulas) and try to read them in every morning .

3-Be clear with your goal(PSU or IIT) ,it will motivate you and helps you to keep you going.

4-Every day in the morning after waking up plan your whole Day (decided number of topics you are going to study and revise) and do it.

5- Try to solve minimum of 30–40 Questions everyday.

6-Never leave the Previous Year papers (They are not important but give idea about for what you are preparing).

7-Complete the syllabus before the (November to December) and join at least 2 Test series .

Bonus TIP(For any examination)- Follow two types of people

1st-The people who are already crack that exam (Toppers)- they will teach you what to do for crack the competitive exam.

2nd-The people who just crack or Failed in that exam

Yes, that's correct, they will not teach you what to do for cracking the competitive exam.

But you can learn more crucial things from them.

Like “What not to do “ during your preparation.

Summary-

Topper can teach “What to do”.

But loser can teach you “what not to do”.

Voila “both are equally important”.

All the best .
