JEE Main is one of the most highly sought-after examinations in the country. The JEE Main examination is conducted by the National Testing Agency to determine individual students’ ability for pursuing engineering courses in some of the best and top technical institutes in the country. To crack a highly competitive exam like JEE, smart preparation, hard work and dedication is required. JEE Main Paper includes three separate subjects, that is Physics, Chemistry and Mathematics. The JEE Main Physics portion of the syllabus is the most tricky and difficult section for a lot of students... Students can download the free PDF from JEE Main Gravitation Important Questions Physics from the Vedantu website.

The JEE Main paper includes 25 questions. In the Physics section, it carries 4 marks each. The JEE Main syllabus for Physics is huge as it includes chapters from Classes 11 and 12. You need to be thoroughly prepared. However, if one has a list of the important questions with you, it makes the preparation a little easier for the students.
We, at Vedantu, have worked with our core JEE team to provide students with all the questions that they must solve to gain practice for the Physics section of the exam. These important questions are solved by our experienced teachers and expert JEE tutors who have years of experience in training students for national-level examinations.

  • Cover the complete syllabus. Although the JEE syllabus is quite lengthy, students are encouraged to cover it every time so they can be thoroughly prepared for any questions.

  • Solve an array of difficult and varied questions. Mathematical subjects can be tricky for students as many types of questions can be asked. 

  • Write as many test series as possible. The only tool that can help augment your preparation of the JEE Mains and Advanced is test series and practice. Aspirants should not be disheartened if they score poorly in the practice test.

  • Identify your weak spots, and work extra hard on them. 

2. What is the Mode of Examination for Joint Entrance Examination (JEE) Mains and Advanced?

The Joint Entrance Examination (JEE) Main exam consists of two papers: Paper 1 & Paper 2. Paper 1 is specifically for Bachelor of Technology (B.Tech) and Bachelor of Engineering (BE) degrees. It is conducted through online mode. While Paper 2 is for the Bachelor of Architecture (B.Arch) and the Bachelor of Planning (B.Planning) degree. It is taken through offline mode only.

Joint Entrance Examination (JEE) Advanced Examination consists of two papers: Paper 1 & Paper 2. Advanced exams are held through online mode only. Students are required to appear in both Paper 1 & Paper 2 exams.

3. How to download the JEE MAIN Question Paper on chapter Optics?

To download the Joint Entrance Examination (JEE) Mains Question Paper on chapter Optics, students can go to the Vedantu website and type it on the search bar. Alternatively, the aspirants can click here to access it. After opening the link, click on the ‘Download PDF’ option. You can also find an array of IIT JEE preparation materials on the website. Students are encouraged to solve multiple question papers to have the required level of practice for successfully clearing the examination.

4. Who can write the Joint Entrance Examination (JEE) Mains and Advanced? 

The National Testing Agency (NTA) is responsible for declaring the eligibility for the JEE Main exam and the criteria.
