I have about 3 months left for jee main.I can done my bord level question very well.But I have problem in some jee que.what to do now.

Try to solve previous year questions and see solutions if required. Make a proper schedule.. Read theory and do questions of each chapter one by one from jee archives.. Take extra time from teacher to take doubts or post your doubt here.. Just hard work is required in proper manner

In order to solve JEE level questions make sure your concepts are clear. If your base is strong you can easily solve any type of question.

You can focus on important topics as well which carries more weightage in the exam. Practice is a key to success. You should solve as many as MCQs for your practice.

You can also refer to previous year papers to understand the exam pattern and level of questions.

Solve as many as mock test series for your preparation. Make sure you analyse your paper to overcome your mistakes. You should always learn from your mistakes and try not to repeat them. You should be aware of your strength and weakness and you should work upon them.

All the best for your preparation and exam!!
