it will really be much more difficult to say anything before the counseling but as per the category rank.... clearly speaking there is  very few probability that you can get nit up to 5-6th round of counseling in any any branch .after that in 7th round, last  round there may be the hope but that too less.

and if you are going for csab counseling there  may be the seat left by any student or anyother vacant seat that may be alloted to you.

while counseling don't keep the limited college option else you may not get any college arrange all nit as per your priority and interest.on other side you will have to accept the college that will be alloted to you in second round of csab counseling else no refund will be made so only keep only the college that you may accept.

better you focus on grabbing more mark to end this few probability here .and also it depends on the quota that where are you belonging from...more chances in your own state nit ...

good luck!!
