Hii
First you have to register online for 1st round counselling and according to marks you scored relative to cut off you will be given a stream and college and if your score or ranknis not up-to cut off
Then second counselling session will be there herebif you are under cut off you are allowed with college and stream and if less than then have to attend third counselling same procedure takes place here as well
If you get under cut off you get college else and attend classes else you are not qualified for that college and have to assess other options
