Hey 

Sorry to Disappoint you but you are not eligible for the exam as the minimum aggregate marks required att your +2 level are 75% and 60% an above in all the subjects .

I am sorry to say that  you are not eligible for bitsat. For bitsat you need an aggregate of 75% in PCM and 60% in English.

If you fullfill the below criteria then only you would be eligible -
Aggregate marks of 75% should have been scored collectively in the three subjects. 60% marks should also have been scored separately in each of the subject i.e. pcm

Which board you are talking about?
