CBSE

You are already heavily loaded because of Physics, Chemistry, Maths and Biology. Why do you want to take additional load by taking computer science? You are eligible for seeking admission in B.Tech CSE or IT even without computer science as an additional subject in 10+2, but if you are confident of taking load please go ahead with CS as an additional subject.

As you are in last month of admission session for B.Tech so there is approximately no entrance exam left all are over almost. so your 12th score is good so you try in counseling of college through your 12th marks.

Sorry to say, but without clearing your class 12th, you cannot get admission in a college. The minimum eligibility is +2.

The best college would be NIEM, Noida for event management.
Good Luck.

Hello Akshay,
Admissions in Maharashtra are based on marks obtained in MHT CET. Of course some seats are reserved for all India quota and are filled through JEE Mains. If you have done any of the above, you have chance.
