During the last few preparation days, you should focus on the revision part. Also, you should study the topics which carry more weightage in the exam. It has been analyzed that, 71 percent questions in the JEE Main exam are asked from 22 percent of the syllabus. You can prepare these topics thoroughly as it is practically not possible to complete the whole syllabus from the beginning during these last days.

Solve previous year question papers and mock tests. It wikll help in enhancing your speed as well as accuracy.

Make an effective study plan and study whole heartedly with concentration and dedication. With best of your efforts and smart preparation, you can definitely get a seat in any decent engineering college.
