Hi, hope you are doing well.

In order to prepare for ISI 2022, you need to:

1. Remain confident and focussed.

2. Make a proper time table, keeping 2 hours for break. You should include 1 hour for revision and 1 hour for preparing your weak areas.

3. Eat healthy and sleep should be adequate.

4. Go through complete syllabus and exam pattern.

5. Make short notes on important concepts.

6. Practice previous years question papers.

A few top coaching centres for ISI in Kolkata are O2 Academia, Slate N Chalk Academy, Institute for Mathematics by Debjani Dutta, Vivek Edu Centre and a lot more.
