Bunty, we do see that you belong to Maharashtra and you are an Engineering Aspirant. So there are JEE Mains, MHT CET and TNEA among the options that you have to study engineering.

To qualify for JEE Mains, there is no minimum aggregate criteria. But if you want to join NITs, IIITs or CFTIs then you should score a minimum aggregate of 75% only in your 12th. 11th marks aren't considered. And then to appear for JEE Advanced which is the gateway for admission to IITs, you will need to fulfill the 75% aggregate condition. Now it is 75% for General Category and 65% for Reserved Categories. So how much you score in 12th is what matters to secure your eligibility for NITs, IIITs, CFTIs and JEE Advanced.

TNEA is the counselliing process for admission to Engineering Colleges of Anna University, Tamilnadu. The admissions are based on marks scored in the qualifying examination which is the 12th. There is no minimum aggregate as eligibility criteria here but if you belong to Maharashtra and want to pick up a College in Tamilnadu, you will need atleast 90% and above.
