Dear Kashif, the rule is that you should have completed your 10+2 atleast by the time of counselling and admission because you will have to submit proof of your 12th pass. So, if you qualify in NEET and you clear your 10+2 board exams atleast by then, you will be considered for admission and counselling. But the registration and choice filling will tentatively start from 2nd week of June and this process will close tentatively by June 3rd. So to be honest, its like walking on egg shells. Neverthless, we wpuld suggest you give it your best shot.
