Hello Aspirant,

See there are some documents which you have to separately upload for JEE-Advance and those documents are like your marksheets and then category certificate (if not available then declaration) and if you don't possess any additional sub category then leave that block and move on but if you belongs to then you have to upload a certificate of that.

For complete process of JEE-Advance application refer to the link given below :-

You can also use JEE-Main College Predictor to predict your college on the basis of your JEE-Main result :-

I hope this information helps you.

Good Luck!!
