Dear Ritika, AIIMS has its own entrance examination for MBBS. You need to appear for their entrance examination and if you clear the examination, you will get into AIIMS. However to get into Sadadurjung or CMC, you need to write NEET exam. As BHMS doesn't have Physics, Chemistry and Biology/Biotechnology as its subjects, your highest qualification will be +2 and your qualification code is 02. Hope this helps!
