For most CET exams, you don't need to complete the admission process before the exam. You first need to take the exam and wait for the results. After the results are declared, colleges will release their cutoff ranks, and based on your exam score and rank, you can apply to specific colleges through counseling. The admission process typically involves document verification and seat allocation. So, admissions are based on your exam results, not before. Keep an eye on official notifications for specific dates.
