Dear Bhagya, provided you qualify for NEET and get a seat in the counselling, you can join MBBS. The minimum qualification for appearing for NEET is that you should have passed your 10+2. There are candidates who complete their B.Sc also appear for NEET in pursuit of becoming a Doctor. So your current studies dont harm your wish of appearing for NEET and joining MBBS. Once you get a seat in Medicine, you need to tske a TC from your current college so as to join Medical College.
