According to the NTA Examination Calendar for the Academic Year 2024 - 25, the JEE Main 2024 Session 1 will be organised between 24th January, 2024 and 1st February, 2024 and the JEE Main 2024 Session 2 will be organised between 1st April, 2024 and 15th April, 2024.

The Joint Entrance Examination, known as JEE (Main), consists of two separate papers. Those who pass Paper 1 can apply for admission to Undergraduate Engineering Programs such as B.E./B.Tech. in National Institutes of Technology (NITs), Indian Institutes of Information Technology (IIITs), other Centrally Funded Technical Institutions (CFTIs), as well as institutions and universities supported or acknowledged by participating State Governments. Students who meet the requirements of JEE (Main) can take the JEE (Advanced), which is the entry test for enrollment into Indian Institutes of Technology (IITs). Paper 2 of the JEE (Main) is organised for individuals who wish to pursue B. Arch and B. Planning courses in various universities nationwide.

Physics is one of the core subjects in the JEE (Main) Examination. Students must be thorough with the physics syllabus to be aware of the potential questions that can be encountered in the JEE (Main) exam. The syllabus comprises 21 units with details about the different concepts covered in each unit. It is observed that questions are asked from every unit in the syllabus. Thus, students must try to cover all the units and strategise their preparation such that they get enough time for multiple revisions. This article provides a detailed syllabus of physics. The link to download the pdf is also available at the end of the article.

While preparing for the physics exam, the students must focus on keeping enough time for revision and test series. Revision will help in better understanding and preparation for the examination and the test series will also help the students in gaining confidence for the examination. The students must try to see the practice tests with the same seriousness as the main examination. The students must also try to complete the practice tests within the time limit and keep half an hour out of the test duration for the revision of the tests to ensure that the correct answers are marked. The students must not try to give more than 7 minutes to a question that they are unable to solve. The aim must be to try and attempt the maximum questions with correct answers and the questions for which answers could not be found could be tried at the end if the time is left.

Students should place a higher emphasis on comprehending the material rather than becoming overly concerned about their grades, as grades are a supplementary reflection of understanding. Familiarity with the exam structure and grading criteria is of utmost importance. In competitive exams like the JEE Main, students should avoid making guesses without sufficient confidence, given the possibility of negative marking, which could lower their scores. Therefore, it's advisable to abstain from answering a question unless they have a reasonable assurance. Effective preparation directly correlates with improved results, leading to a sense of fulfillment and serenity. We extend our best wishes to all students for their journey of preparation and the upcoming competitive exams.
