Good morning Deepak,

I hope you are doing well. As per your mentioned query , JEE exam is a national level of exam which is quite tough to crack. But with right direction and dedication you can clear this exam in first attempt. Here i am sharing some tips:

1. Firstly, analyse the syllabus and try to know which chapters are important or which are less important.
2. Start with basics always follow NCERT first as this makes your foundation strong.
3. Make a productive schedule for your studies.
4. Give time atleast 7-8 hours daily with full dedication.
5. Give time more to those topics that are weak for you.
6. Practice previous year question papers so that you will get an idea of questions coming in exam.
7. Practice more and more. Use standard books too for your preparation.
8. Give mocks and analyse your mistakes.
9. Atlast revision is important. Revise weekly whatever you studied in whole week.
