Dear Aksa, you havent mentioned your Category. Neverthless, as of now there is no upper age limit for NEET. Which means there is no cap on no.of attempts for NEET. There are 2 criteria. One is you should be atleast 17 years by December 31st of the year of admission and the second is you should score an aggregate of 50% in Physics, Chemistry and Biology in your 10+2. It is 50% for General Category, 45% for PWD and 40% for SC,ST,OBC. If you fulfill these criteria, you are eligible for NEET at 10+2 level. Now because you have completed your B.Sc, the criteria are a little different. You should have studied any 2 subjects among Physics, Chemistry, Biology/Biotechnology. Now you have Chemistry and BioChemistry apart from other subjects. That puts you slightly off the edge. With this qualification you cannot alpear for NEET. Because you dont have a second required subject among Physics and Biology.
