It is very important to study about the courses available in all the participating institutes.

Check whether the fee is affordable. Some institutes and programs have specific restrictions or special eligibility. Please ensure that you fulfill those special eligibility / restrictions.
What is the best strategy of choice filling?
Each choice of institute or branch must be such that you know completely what you are asking for. Include only those choices in your list where you are really prepared to go if you get an allotment. One must refrain from gambling or take-a-chance approaches. No choice should be included in a half-hearted manner. It should not happen that after getting an allotment you say Oh! I did not want it. If that is so, it should not have been in the list of choices. Maintaining strict order of preference is also very important. Assume that what you really want is at no. 17 in your list but you get choice no. 13. In the subsequent rounds, choice no. 1 to 12 only will be considered.

I had got a seat of the NIT+ System in JoSAA Rounds and I had kept my willingness option as FLOAT/ SLIDE/FREEZE. I have completed all the formalities and have paid the Partial Admission Fee.

I was allocated and confirmed a seat in a certain round in an Institute of NIT+system. I have now been allocated another seat of higher preference in my choice list in another Institute of NIT+system. Do I need to report again online?
No, if you have already completed all the steps of online reporting process in a certain round in reporting centre of NIT+system and you have been allocated another seat of higher preference in your choice list in another Institute of NIT+system, you don’t have to repeat the online reporting process.
Can I exercise Willingness option in CSAB Special Round-2?
No. As it is the last round, the default and the only option is FREEZE.
I am not interested in the seat offered in CSAB-Special Round 1. Can I participate in seat allotment in further rounds without accepting the seat now?
No. First of all, do not fill-in the choices for the courses that you are not interested. If you do not accept the seat allocated in the CSAB-Special Round-1 and do not complete the steps of document verification and IAF-II payment, you will be out from the seat allotment process and the allocated seat will be CANCELLED. However, you may opt for the SURRENDER option wherein you can surrender the currently allocated seat and participate in the 2nd Round of CSAB-Special Round. In case you opt for SURRENDER, you will not be required to pay IAF-II unless and until allocated a new seat in the 2nd (final) round of the CSAB-Special Round.

I have been offered a seat in the 1st Round of CSAB-Special Round of allotment. I want my lower choices in the choice list to be considered in the 2nd Round. Can I get the lower choices in the 2nd Round of CSAB-Special Round?
No. The seat allocation will be in the order of preference. If a seat is allocated in the 1st Round, the subsequent seat allocation will be from the higher choices only.
I do not have some of the requisite documents for uploading and/or have difficulty in obtaining the documents and therefore, it is difficult for me to upload documents as per the Schedule of the CSAB-Special Round. Can I upload my documents later or verify at the time of admission?
No. The seat allocation process follows a strict timeline. The entire process is online and computer operated.
