There is no universal preference order list for JoSAA counseling. Instead, you are advised to provide a preference order on the basis of your requirements and JEE rank. Here are some useful tips to help you make a preference order list: (a) Check the previous year's opening and closing rank of the IIT, NIT, or IIIT you want to put in preference order. You can check it on the Shiksha website, which provides the closing rank of every IIT, NIT, IIIT, and GFTIS. (b) If you are confused between two colleges, prefer college having higher rank in NIRF. (c) If you are confused between two branches, then prefer a college with better placement for the same branch. (d) You can also compare colleges on placement and facility parameters with the help of reliable student reviews available on the Shiksha website for that college. Normally, students with higher rank prefer:
1. IIT Bombay
2. IIT Delhi
3. IIT Kanpur or IIT Madras
4. IIT Kharagpur and so on
than in NITs
1. NIT, Surat
2. NIT, Tiruchirappalli
3. NIT, Warangal
4. Motilal Nehru NIT, Allahabad, and so on. You have to keep in mind your rank as the possibility of getting college and branch will highly depend on your rank. For example, the CSE branch usually has a higher cutoff than the mechanical branch in the same institute.
