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.

With 77 percentile, getting a seat is possible, but it will depend on the branch and the admission cycle. For highly demanded branches like CSE, the chances are usually quite low at that percentile. But for some core or less competitive branches, there may still be opportunities.

If you are OBC candidate then you can
1) Fill JoSSA — try for NIT Manipur/Nagaland/Mizoram in Civil or Mechanical
2) Participate in CSAB — extra chance
3) Don't skip state counselling — OBC quota there can be very beneficial
4) Apply to NSUT/YMCA — placements rival many NITs
