Dear sir, I can't get any college in csab round 1.can I have to do any thing to participate in second round?

Hello Rahul, do not worry if you have not got any seat from 1st round counselling, based on your rank you can get seats in the subsequent 2nd, 3rd etc rounds of CSAB counselling. Even if you dont, do not lose hope and go for private colleges or retake the JEE exams once again with better preparations.

Dear student, as you have not got a seat in the first round of Csab Counselling, your registration will be valid in in the second round. However, you will not be allowed to make the choice filling once again for the second round freshly. The choices you have filled in the round will be retained back and the colleges will be alloted accordingly. You can for sure of out of the counselling process if you do not wish to get that allotted seat in the rest of the colleges.
