I have given cuet 2025 exam ..in which I gave the exam of physics, chemistry, biology...and in my 12th I had PCMB ... So can I persue physics honours though I didn't choose maths in CUET exam ...???

Since you had Maths in Class 12 (PCMB) but did not choose Maths as a subject in CUET 2025, these are the two possibilities:

1. You are academically eligible because you studied Physics, Chemistry, and Maths in 12th, and most universities require Maths in 12th for Physics Honours.
2. Most central universities offering BSc (Hons) in Physics require you to appear for Mathematics in CUET, along with Physics (and sometimes Chemistry), because CUET scores are used for merit calculation.

So, you may not be eligible for Physics Honours in most central universities like DU, BHU, JNU, etc. Some state/private universities or non-CUET colleges may still admit you based on Class 12 marks and your CUET Physics score alone, but they are rare for Physics Hons.
