JEE Main 2021 Preparation Strategy

With the JEE Main Exam on the horizon, candidates might be dealing with stress and anxiety related to the exam. Stress and anxiety are a part and parcel of any exam preparation process, however, they can prove to be disastrous in a situation where they overwhelm a candidate and their ability to score well in the exam. For this reason, it is essential for students to follow and stick to a strategy that will help them write the exam well. Below, we have listed a list of tips that candidates can employ as part of their preparation strategy for JEE Main 2021.

1. Stick To NCERT Books For Core Subjects

For the core subjects of Mathematics, Chemistry and Physics, candidates should treat NCERT as their gospel. Students can rely on the NCERT textbooks, as well as rely on the tips and tricks for preparation prescribed by their coaching institutes, to have a fair shot at getting a good score in the JEE Main 2021 exam. They should not only make sure to go through every topic and practice every formula but also focus on the most commonly asked questions in the exams.

2. Revise All The Topics

Candidates must go through the summary and key concepts listed at the end of each chapter. By doing this, candidates will get a better idea of the important topics, as well as their ability to recall those topics. Candidates must then focus on the topics that they can't recall well and pay special attention to those chapters.

3. Practice Mock Tests/Previous Years Question Papers

Attempting mock tests and solving the question papers from previous years can give candidates an idea of what to expect from the exam. By recreating the conditions of the exam; setting up your desk and timing yourself (time is taken for each section, and time is taken to complete the mock test), candidates can increase their chances of getting a good score in the exam, along with having a confidence boost on the day of the exam.

4. Make Notes

Preparing notes will help students recall the topics better. The syllabus for JEE Mains is vast, and candidates might easily forget (or leave out) certain topics which can be detrimental to a candidate's performance in the exam. Making notes, especially of the important topics, can help candidates better prepare for the exam. Furthermore, it is advisable for candidates to avoid any last-minute study before the exam and only rely on their notes for the final revision.

5. Avoid Any Last-Minute Preparation

This means, don't study any new topics in the last days leading up to the exam. This can cause a lot of confusion and lead to the candidate forgetting the topics that they've spent so much time studying. It is advisable for candidates to rely on the notes that they've created in preparation for the exam. It will prove to be absolutely futile and counter-productive to try and study new topics at the last minute.

6. Maintain A Healthy Lifestyle

Maintaining a good sleep cycle, eating well, and exercising are habits that help candidates be sharp on the day of the exam. It makes no sense for a candidate to prepare extremely well, only to experience fatigue while writing the exam. Maintaining a healthy lifestyle can be a little tedious, especially for young candidates putting in the effort to prepare for the exam, but a candidate with a healthy lifestyle can have a serious edge over a candidate with poor lifestyle choices.
