Last Minutes Preparation Tips for JEE Main 2021 25 July Exam
Candidates can check the last minute preparation tips for JEE Main 2021 exam that will be held on July 25.
Focus on Revision
Revision is very important before the examination. Candidates are advised to spend most of their time revising the topics and concepts that they have studied during their preparation period. This will help the candidates retain what they have studied and positively influence their performance in the JEE Main 2021 examination.
Do Not Start New Topics
The golden rule of last-minute preparation tips is that new topics should never be studied just before the examination. By studying new topics, the candidates will have higher chances of getting confused about the concepts and formulas. Instead, the candidates should focus on strengthening their grasp on the topics that they have previously studied and revised.
Solve Mock Tests
Mock tests are a great way to test the progress of exam preparation. Since the mock tests will be similar to the question paper, the candidates will be able to familiarize themselves with how the exam will be conducted. By attempting mock tests, the candidates will also be able to identify their commonly made mistakes and work on it.
Work on Time Management
While preparing the JEE Main syllabus is important, the candidates will also have to work on their time management skills. Since the candidates have to answer many questions in a certain duration, there are chances that they might miss some due to time restraints. However, if the candidates have practiced solving past papers within the time limit then they will be able to perform well. During the exam, candidates are advised to allot a certain time for every section so that they can finish the exam within the given duration.
Be Healthy
It is very important for the candidates to be healthy both mentally and physically during the exam. This will help them to improve their performance in the examination. Candidates are advised to get enough sleep and not indulge in social media. Intake of healthy food is necessary to stay in the best shape.
