JEE MAIN 2021 Preparation Plan

Plan and Revise: Chart out a plan beforehand and adhere to it. Mark on the calendar the topics required to cover. Just keep 3-4 days blank as these days might be necessary as extra time to cover certain topics. For just a day prior to the exam, do not keep a very difficult topic as that might only escalate nervousness.

Use notes now: If a candidate thinks he/she can pick up a new book to help him/her out now, it is wrong. The last moment revision calls for self-made flashcards or notes. So, it is necessary for students to keep notes for each subject in their own handwriting. During revision, studying from self-written notes has always proved to be more effective than books.

Solve mock tests: Use this time to get prepared for the hands-on experience. If an aspirant has already solved previous year papers, solve JEE Main Mock Tests online. Also remember that whenever solving mock tests, try to do it within the time limit. Speed is the most important factor that can determine the score.

JEE Main Revision is the most important part of the preparation now. So do it right and crack the exam!

Plan your weekly and daily timetable: It is not humanly possible to finish the complete syllabus in a day. So unless a student is a flash don’t think that “Today I will finish the entire syllabus!”

Make a weekly timetable in which precisely note down the chapters to solve from so-and-so book; the number of sample papers to solve and revision. Also, create a day-wise timetable outlining important subjects for study and goals.

Do not get tensed frequently: Be happy and stay calm. Any engineering entrance exam is not the end of the world. The candidates need to stay focused and repeatedly tell themselves that they can do it!

Ignore pesky and bothersome relatives or so-called well-wishers who keep bothering about marks or taunting about performance.

Give Best and Work Hard.
