JEE Main

I think it is not possible to get a seat in CBIT.

I think not possible to get a seat in CBIT, may be you can try for chemical or bio-tech.

It depends on the rank you get, go through this link for colleges accepting Mains marks.

It is not possible with this rank. You should score maximum to get admission. They have various branches but every branch's cut-off is high and not below JEE Mains score of 240.
If you score 250+ then hope to get a branch but not CS.

All government colleges take admissions on the basis of the entrance exams result. Since you didn't give one it is highly unlikely now. One thing that you can do and don't place your hope on it. You can wait and later contact the colleges to see if they have any seats vacant or they are conducting spot counselling.

Don't worry, you are having 320 marks in JEE main, tou can try many private good colleges in south india, who takes only JEE main marks, like bannari amman college and many more!

Government colleges don't give admission only on the basis of +2 marks. So, I would suggest you to explore your possibilities in top private colleges to make best out of it.
