CBSE 12th

You can go for BBA. You can even do business without any degree. My brother is an engineer in Infosys. He left that job and opened a business and now he is earning really good, even without any specialization and degree.

There are total 2 attempts to appear for BITSAT. So if you have missed then you can only appear in 2018.

BBA is about business management and B.Com is all about accounts, economics and business studies. It's totally based on your field of interest.

Yes, you can apply and rest will be the cutoff that will decide if you get admission in the specific college or not.

DAIICT and Nirma University are the best amongst the all and amongst these 2, DAIICT has no competition.

Hi,
They don't consider 10th marks but in 12th board exam you need to have at least 75% overall and an aggregate in PCM should also be 75%. Otherwise, even if you clear JEE main and advanced you will not be eligible to get admission in any NIT or IIT.

If you have already done 11th with science you cannot move to 12th for humanities however you can opt humanities in BA. If you opt humanities in Bachelor in Delhi university, there will be additional 2.5 percent penalty like if cut off for a 12th humanities is 92 percent, you have to score 95.5 percent however in Mumbai University 30% students have quota to opt from.other than the same faculties.
