JEE Main Physics Syllabus Preparation Tips

The Physics section of the JEE Main exam, is considered to be the toughest of the three subjects. So experts believe that if a candidate can score well in JEE Main, then their chances of topping the ranks increase significantly. To help students smartly complete JEE Main Physics syllabus, we have developed some valuable tips

Few Physics specific preparation tips:

  • Topic-wise short format notes of facts and formulas: Crucial strategy to follow when studying, revising, and solving problems. This strategy might seem a basic one, but it has a high impact on improving your memory and retaining core concepts.
  • Usage of visual memory: This strategy has worked for many students. Physics has a lot of application-based learning. You can build your visual memory to connect concepts and formulas from the JEE Main Physics syllabus to real-world situations. This will help you remember things easily and for a longer period because you can relate to the process behind these concepts.
  • Daily 3 hours of Physics: Split your days and weeks in three. Give equal importance and time to Physics, Chemistry and Mathematics. 3 hrs a day should be good for JEE Main Physics syllabus completion. In your strategy, also devote separate time to work on weaker Physics topics.

Other preparation tips:

  • Always keep in mind the JEE Main Physics syllabus and fully complete it.
  • Solve questions of higher levels from good books.
  • Analyse and solve as many previous years’ JEE Main question papers as possible.
  • Attend mock tests regularly, possibly one per week.
  • Be thorough with NCERT.
  • Regular revision of the previously studied JEE Main concepts is essential to prevent losing touch with concepts.
  • Understand the JEE Main question paper pattern and prepare a pre-examination strategy.
  • Having a positive attitude is very important for success in the JEE Main exam. 
  • Maintaining a healthy lifestyle while preparing for JEE Main will give a healthy outlook towards life and enhance mental stability. 
  • Keeping aside some time every day for self-study is of key importance.

Benefits of Solving JEE Main Physics Question Paper:

  • Students can develop a fair understanding of JEE Main by solving the JEE Main question paper with solutions.
  • Solving JEE Main previous papers helps students understand the JEE Main exam pattern. Extramarks has collated past many years’ question papers covering all the JEE Main Physics syllabus topics.
  • Students who solve previous years’ papers are more likely to perform well in exams.
  • Solving the JEE Main question paper helps students boost speed and accuracy.
  • The JEE Main question papers help in improving time management.
  • Analysis of the JEE Main question paper will help familiarise students with the exam pattern and help score better marks. 

Guidelines for Exam Day:

  • Candidates should go to the examination centre one day in advance. They should familiarise themselves with the place, time taken to travel, etc. so that they are adequately familiar and have no problems on the date of exams.
  • They should plan to reach the examination hall one hour earlier on the exam date. Getting to the exam centre an hour earlier helps avoid last-minute issues. 
  • Candidates should carry a hard copy of their JEE Main admit card and a valid photo ID proof (PAN Card, Driving Licence, Voter ID, Passport, Aadhaar Card with Photograph, E-Aadhar, Ration Card, Aadhaar Enrolment Number with Photo).
  • No electronic devices, jewellery, watches, and so on are allowed into the exam hall. 

Do’s and Don’ts for JEE Main Exam

Given below are the do’s and don’ts for the JEE Main exam. 

Do’s:

  • Patiently read the question at least two times. Do not panic if you don’t get the question the first time. Read it carefully and slowly again. In many cases, the information that can hint at the answer is hidden in the problem statement.
  • Start the question paper by attempting the more straightforward and medium questions of the JEE Main question paper first, which will help boost the candidate’s morale and help in increasing the JEE Main score. 
  • If you get a tricky and time-consuming question, please move to the next question, and translate that, as there is a similar marking for all questions. You can come back to solve the slightly tricky questions once all easy questions are solved;
  • Candidates are advised to carry their transparent water bottles and transparent ballpoint pen.

Don’ts:

  • The candidates are advised not to solve questions in haste as many silly mistakes occur.
  • Anxiety during the exam is a significant factor and brings down students’ scores. 
  • Wearing uncomfortable clothes during exams will decrease the productivity of the candidate.

5. Is NCERT enough for JEE Main Physics syllabus preparation?

The JEE Main exam is critical for students who aspire to do engineering in top Indian institutes. There are limited seats, and the JEE Main Physics syllabus is vast. 

JEE Examinations are based on the syllabus of NCERT, and often, questions from NCERT books appear in the JEE Main exam. Therefore, those that have practised well and are thorough with the basic concepts from NCERT should have a very high ability to solve most questions with a high level of accuracy.

The official JEE Main Physics syllabus and NCERT books cover similar topics, and hence NCERT books are essential for JEE Main preparations. Moreover, the syllabus of JEE Main and that of CBSE’s Class 11 and 12 board is almost the same. Therefore, students can consider NCERT books one of the best reference materials.

However, this does not mean that NCERT books are enough. Students must use the NCERT as their basics, be exceptionally well versed and thorough with the NCERT books, and subsequently use the rest of the books for a higher-order preparation for achieving the rank and institute of their choice. 

6. What is required to score good marks in JEE Main Physics?

Below are a few tips for students to score higher marks in JEE Main Physics:

  • Practice, practice, practice. That is one of the primary keys to successful competitive exams such as JEE Main exams. Prepare your study and revision material by referring to the JEE Main Physics syllabus. Ensure that you have reference books, topic notes, question papers with answer keys, mock test questions, etc., covering all topics from the syllabus.
  • Develop innovative study slots in your daily timetable for a subject like Physics. For example, JEE Main includes many application-based questions that ideally would be solved by doing numerous similar types of questions and training your brain to work faster on such questions.  
  • Revision is another critical area. Identify your weaknesses and tackle them by regular revision and concept clearing sessions. Ensure that you revise the complete JEE Main Physics syllabus.
  • While you build your rigour for the end months of the exam, do not ignore your health and mental wellbeing. Engage in meditation or relaxation exercises to keep your mind and body from stressful situations.
