I am in 11th standard preparing for JEE 2023. My classes started in May but I have wasted my time till now. I haven't been doing well in my coaching tests and also in school exams. I also have backlogs. Can I still crack JEE with a rank under 2000 if I start from October? If so can I know some tips?

Start studying 2 subjects each day giving equal time to both like 2 or 3 hours each. How many hours a student can study daily can vary from person to person but whatever time you give, make sure you do it without any disturbance and distractions. Keep your phone away unless absolutely necessary while studying. For focused study with concentration and efficiency you need:
1. A systematic schedule
2. Proper study techniques
3. Repeated revision
4. Enough practice
5. Use mind maps to recover easily from memory
6. Relaxation techniques

You will definitely be able to complete your course in time for jee mains 2023 if you follow these tips. For a rank above 2000, make sure you practice previous year papers and do high level questions from each topic.

In jee mains, 45% syllabus is from class 11 and 55% from class 12. So, while studying for your class 11 you can include some high level problems for each topic to get you prepared for jee mains along with it. Specially in chemistry portion, majority of the questions are from ncert directly, make sure you go through it thoroughly and revise periodically.
