I want to clearly 12 and coming amu joint for bba and bcom

If you are going to clear Class 12 and wish to join Aligarh Muslim University (AMU) for BBA or BCom, you need to appear for the AMU Entrance Test (CUET-UG optional for some courses).

Pass 12th with at least 50% marks in any stream. Based on AMU Entrance Test rank (or CUET score if accepted that year).
Start preparing early — AMU’s BBA and BCom cutoffs are usually high due to competition.
