IIIT

Friend, there is no chance of getting NITs or IITs. You can get state government colleges or you can go for other private colleges available.

You should prefer IT at IIIT Lucknow.

No, you'll not get any of the above-mentioned colleges (assuming that you are general ). You are likely to get into one of the private universities or autonomous state government institutes.

Can I know the rank, because mostly the colleges are predictable only by the rank. If you got higher rank also I suggest you to go for JOSAA because in the previous year many seats were vacant due to lack of knowledge during options entry. If you're lucky enough you get one of them.

Good luck.

I would suggest you to go for IIITs because after IITs and NITs, IIITs come.

Maybe. Are you from SC/ST or another category?

You cannot get any NIT or IIIT but you have another options for good private engineering colleges where you can get admission easily. Otherwise, you should go through the state counselling procedure for the government college or the best private college. All the best.
Thank you.
