In case you forgot to lock your application preferences in CAP Part 2, there is no reason to get panicked. Whatever options you have chosen the system locks automatically after the deadline. Thus, your options will be taken into consideration even without manual locking and seat allotment will be given. All you have to do is to settle down on those preferences before the clock strikes so that you can eliminate last-minute problems. Always remember the deadlines- this would help you be a step ahead in the admission process.
