Hi.

If you apply with JEE Main scores, CU primarily considers your JEE Main percentile / AIR for admission.

12th marks are generally secondary in this case — mostly used for eligibility criteria (like minimum 50–60% in PCM or aggregate, depending on branch).

High JEE scores can also qualify you for JEE-based scholarships at CU.

Hi.

If your 12th result has not been announced yet then 

Upload expected / provisional marks for now.

Final admission depends on the official 12th mark sheet after results are announced.

Colleges are used to this situation, especially for students applying in early cycles.

Hi.

AIIMS is primarily a medical college/university (undergraduate, postgraduate, super-speciality, etc.) + a hospital. 

Its courses begin after Class 12 — i.e. you must have completed 12th standard (10+2) to be eligible for entry into courses like MBBS, B.Sc., etc. 

The official course list of AIIMS includes medical and allied health degrees — not school-level classes (11th / 12th) as per its academic catalogue.

Thus, AIIMS itself does not run 11th and 12th standard as a school.
