After you get your ranks and scorecard of NEET you attend the counselling according to the forms of different colleges you have filled.
Then on the particular day of counselling you go with all the documents (original) as required and submit them and fill another form requiring your rank and scorecard details and submit the originals.
Mind it that the originals you submit will be with the college for 5.5 yrs and thus, don’t forget to get a photocopy of each.
Then you will be called according to your rank and asked to select the college of your choice.
Counselling is nothing to be worried of.
No questions are asked and any doubt in filling the form can be asked to the people concerned.
When you have been alloted a college you are given an appointment letter.
This letter is to be taken to the college and submitted there. Some other forms are filled and the college fees for one session is given and other formalities.
Finally you are given a date for your first day in college!!!
