Hi aspirant,

At first one cannot do diploma and normal class 12th at the same time as it is illegal. In case you have completed your 3 year diploma you can definitely apply for JEE main examination and get admission into your desired college. Now if you have done diploma and after that you are doing internet then also you can apply for the examination as the rule says a candidate is eligible for three continuous years starting from the year he or she appears for the intermediate level examination which is diploma in your case.

Hope it helps!
