JEE Counselling

Nothing will happen, it's your own choice. You will just get colleges on the basis of your JEE Mains rank only.
You can still apply for both JoSSA (for colleges other than IIT's) & JAC (for 4 colleges, NSIT, IIIT, DTU ,IGDTUW ) through your JEE Mains All India Rank.
It is not compulsory to give Advanced.
Al the very best!
Happy to support!

Kapilan, LPU used to participate in JEE counselling but now it doesn't participate in it. But it does give admission on basis of JEE marks.

You have to got 75% marks to be in top 20% percentile of college. But nevertheless, you can get admission in NIT-Raipur. But firstly, there is the first requirement. So, you can go for some integrated course in branch selection and then, the internal sliding, you can get the branch as per the requirement.

I hope you will be in a good college right now. So that it is not possible to answer this question. And the JEE Mains paper 2 results for the year 2017 have also been released.
All the best.

Yes, it depends on all these factors. Not all students go for the top colleges as they will not be deemed eligible so the 2nd round of counselling will be for those who are eligible for admission based on their scores and the colleges they could get.
The chance of getting a good college depends on the seats available.

Once you get a branch in some IIT, you have to confirm that you are accepting the seat. Then that seat is confirmed and can be upgraded, if possible, but once you get a seat, it cannot be lost. Dont worry!

Good luck.

Hi Dear,
You are not eligible for JoSAA -Joint Seat Allotment Authority counselling as you haven't cleared the cutooffs as specified. So either you can try next year or try for private colleges in your state.
