Dear Shivani, there is no option of Seat locking at any these exams that you have mentioned. Admisisons are conducted based on merit list in the selection process. Because these are Institute level entrance exams, you dont have the option of locking a seat.

SNAP: You need to appear for SNAP and score the minimum cut off to be eligible for shortlisting. The shortlisted Candidates have to appear for GE-PIWAT and the final merit list is prepared based on the performance in GE-PIWAT.

IBSAT: The process is similar to that of SNAP. Candidates need to qualify in IBSAT and secure the minimum qualifying marks. Candidates will be shortlisted based on Group Discussion and Personal Interview.

CMAT: AICTE approved Institutions that participate in CMAT will conduct the selection procedure. Candidates will have to appear for Group Discussion and Personal Interview based on the Institution they are interested in joining.
