JoSAA

First you should wait for the document verification process. But since you had freezed once verification done either they'll tell you to wait for 6th round or they can direct you for further processes of that particular college. Hope it helps.

JoSAA choices has been locked. So you can not go for JoSAA counselling. But you can think of CSAB once it starts after JoSAA in which only AIR is considered for counselling. Since your SC rank is this high then your AIR would have been too high so it's like very tough to get CSE/IT. Hope it helps.

For JoSAA Counsiling, candidates must download the e-challan and pay Rs. 35,000 (banking candidates) or Rs 15,000 (Sc/ST/Gen-Pwd. ). Fee can be paid using SBI net bankimg.

As your JEE Mains rank is under 65,000 in general category, it is very tough, to get admission in top NIT and pursue B.Tech from it, so you should prepare for it again. But if your aim is just to get admission in NIT no matter which NIT and which branch, then you msy get admission in it. Like you may get NIT Agartala, NIT Jalandhar, NIT Goa, NIT Hamirpur, NIT Mizoram, but not any branch, some branch like chemical engineering, civil engineering, And if your domicile of state of these NIT, then you will get it, otherwise there is tough to get it.

At this rank you can get admission in many NIT, IIIT, you just have to wait till round 6,7 or even spot round if you want to get a good branch. In top NIT, IIIT you can't get CS with this rank but you can still try your luck in spot round. In NIT which don't come under top 5 you can get admission in ECE, EEE, civil and many more and if you have a Home State quota then you can surely get admission in 1 of the top 5 NIT. Just refer to the previous year cutoff from the respective NITs website you will get a much better idea about cutoffs.

Obviously, it is like not possible for CSE, but you can go to other branches in lower NITs. But once there was around AIR 7 lakh cutoff for IIIT Ranchi. Hope it helps.

For ordering of colleges it should be based on your preferred Branch and college. Basically JoSAA is the counselling body for admission to IITs, NITs, IIITs and GFTIs but with CSAB except rest other colleges are considered for counselling and also in CSAB allotment is done purely on the AIR basis in JEE Main. No preference based on any category. You got a chance to fill up the choice of college again in CSAB. Hope it helps.

Joint Seat Allocation Authority JoSAA has been set up to manage and regulate joint seat allocation for admissions to over 100 institutes, including IITs, NITs, IIITs, and other government-funded technical institutes (other GFTIs). According to the home state quota rule, your domicile state is considered the state from which you have completed your 12th grade board exam. Approximately 50% of seats are reserved for this quota. So if you have completed your 12th grade in Rajasthan, your home state will be Rajasthan even though your domicile state is Jharkhand.
