An 81.93 percentile in CET (Common Entrance Test) can give you a competitive edge, but admission to Computer Engineering or Information Technology programs depends on various factors, including:

1. Institution's Cutoff: Each college has its own cutoff scores, which can vary based on demand, the number of applicants, and the specific program. Some institutions might have higher cutoffs for Computer Engineering and Information Technology.

2. Reservation Quotas: If you fall under any reservation category, it might affect the cutoff and your chances of admission.

3. Availability of Seats: The number of available seats in the specific programs can also influence your chances.
