JEE Main Scores

It's difficult for you to get admission in government colleges for B.Tech with these marks.
But, in which state do you want to take admission?

Yes, it is possible to get a seat. You should apply for all branches to be sure.

It is almost impossible to get a seat in any NIT with your JEE marks. I suggest giving the exams again if you are genuinely interested in studying in one such university.

It is very difficult to get NIT-trichy. You can try applying for colleges in rourkela, durgapur etc with easier cutoffs.

It will be hard to get any state government college as even the counselling of many colleges is about to end and the sessions will probably start from mid of August. But, you can still look for it in your area. But, the best option will be to join any private college because your board percentage and Mains score is too low. And, the private colleges are doing exceptionally well, so you can go for it.

If your general rank is 6213, then u'll easily get IT at IIIT Allahabad because of reservation quota.

Sorry to say but you are not eligible for any of the government colleges including NITs, GFTIs based on your marks.

Yes, you are eligible. You need to visit the campus.

minimum score 180++

It may be hard to get admission with 43 marks in JEE.
