hI reader ,

if you have registered for the 1st round and are alloted a college and you decide against taking it then you can take part in round 2 without any problem.

if you donot fill the choices in round 1 then also you can take part in round 2 but this time you will have to register again in round 2.

i hope this helps

for knowing your chances of getting a college you can refer
