JEE Main Last 10 Years Question Papers with Solutions (2025 to 2015)

BEST REGARDS

Hello,

For JEE Main and JEE Advanced , the cut-offs are lower for ST category students. Here is a simple idea based on recent trends:

  • JEE Main qualification for ST : Around 50–60 marks is usually enough to qualify for JEE Advanced.

  • JEE Advanced qualification for ST : You just need to clear the JEE Main cut-off, then appear for Advanced.

  • To get good NITs or IITs , you will need higher marks.

    • For NITs (Hyderabad or good branches), try for 120+ marks in JEE Main .

    • For IITs , even with ST quota, you should aim for at least 80–100+ marks in JEE Advanced for decent branches.

Since you are from ST category and Hyderabad , you don’t need 300 marks in JEE Main. Try to score as high as possible to get better branches, but even moderate marks can qualify you.

Hope it helps !

Yes, you can. If you do 11th from CBSE in 2025 and 12th from NIOS in 2026, then you are allowed to attempt JEE. NIOS is a valid board, so you can give JEE in 2026 and again in 2027. Just take admission on time and pass your 12th exams.


For the JEE 2026, priority-wise, high weightage chapters include Integral

1. Calculus, Coordinate Geometry, Vectors, 3D Geometry, Complex Numbers, and Quadratic Equations in Maths
