I have registered for CAT 2019 for the first time, i selected the IIMs in the procedure, except that do i need to apply in any other college or that is done after the result is out?

Dear Shivam, different colleges release their cut offs after the CAT results have been announced. So once CAT results have been declared and the colleges release their cut offs, you can shortlist the Coleges that you are interested in and then apply to those colleges separately. In the CAT application, you can only select the IIMs and not other colleges. But given the fact that almost more than 1000 colleges accept CAT scores, make a list of the Colleges you are interested in and follow their official websites to check their cut off percentiles.
