Hello there! Do not panic, if you don't get any allotment. In the second round, you'll definitely be allotted a college from your option form. Those who are given an allotment, are supposed to report to facilitation centers as per guidelines issued by DTE. If not, you will have to resubmit to option form, you can make changes if you like, or , submit the same thing again, and wait for the results of the next CAP round. 

Please revert if you have any queries, all the best!
