Modern Physics Class 12 for JEE Main
Modern Physics focuses on exploring fundamental natures of matter, energy, space and time. It challenges everyday intuition with concepts like wave particle duality and curved space time, which forms basics for technologies like lasers, semiconductors, and nuclear energy.
In JEE Main, Modern Physics often has high weightage and students can secure good marks if they are fully prepared for it. JEE Main chapter-wise weightage topics can be checked to understand which units can be focused on for better results.
Some of the important high weightage chapter of Modern Physics Class 12 are Radioactivity, Semiconductors, Photoelectric Effect, Semiconductor Diode and more.

Not both are not same. But some topics are similar in JEE Main and JEE Advanced. Students who qualify the JEE Main exam and are among the top 250000 students are eligible to take the JEE Advanced. Due to this reason majority of syllabi are the same, but a few extra topics are added in JEE Advanced.
JEE Main is conducted for multiple courses and the syllabus is different for each course. The syllabus of JEE Main Paper 1 (BE/B.Tech) includes class 11 and 12 Physics, Chemistry and Mathematics topics. For JEE Main paper 2A B.Arch the syllabus consists of Mathematics, General Aptitude and Drawing. Similarly, for JEE Main Paper 2B B. Plan the syllabus is Mathematics, General Aptitude and Planning. Candidates can check and download the detailed topics-wise JEE Main syllabus on the Shiksha page as well as on the official website jeemain.nta.nic.in.
How to Prepare for Modern Physics Class 12 chapters?
- First, students should be familiar with chapters included in Modern Physics Class 12 syllabus. Knowing syllabus thoroughly will help them to which topics and concepts will be used to prepare question paper.

Time required to cover JEE Main syllabus changes from one student to another student. In general, to complete the entire JEE Main syllabus, students would require around 1 year. The ideal time to start preparing for JEE Main is class 11 as the syllabus for JEE and class 11-12 is similar. Students who are studying in class 11 can point out the topics that are common in both and pay special emphasis to those topics.
