Build your own shortcuts and ways for problem solving as focus properly on solving the problems on your own, do not look for the solutions without attempting a question. Start with conventional methods of solving, while gradually improving.Try the shortest approach to MCQ/elimination method. Dont compare your performance with others better to do comparison of your present to past performance. While preparing for your studies never ignore your health.Have a printout of your syllabus. You will have to study at least 12 hours. But considering the situation, I would recommend you to go for 15 hours on some days. Also, better to keep all the distraction away like (Whatsapp, Facebook, Insta etc.)

Hope this helps!!!

Your JEE preparation is incomplete without revision. You would have prepared a lot of  notes and flashcards to help with your revision. But your study notes may have a comprehensive overview of a certain topic but your flash cards should be clear and  concise.

You should follow below points for your revision

1- Do not learn anything new. At the time of revision make sure you don't go through any new topic. You should revise your whole syallbus and focus on the important topics.

2- You should go through your self notes or flashcards if you have prepare them.

3- You should pactice a lot. Try to solve as many as mock test series to analyze your preparation level and to know your weak and strong areas. So, you can work upon them.

4- You should also refer previous year papers to know the pattern and difficulty level of the exam.

All the Best!!
