Generally, a CGPA above a certain threshold, usually around 7.5 or 8.0 out of 10, is required for a first-class. However, the exact minimum CGPA for a first class can differ based on the specific regulations of the department and the year of admission.
To know the precise criteria:
* Check the CUSAT website: Look for the academic regulations specifically for your department and year of admission. This is the most reliable source of information.
* Contact your department: The departmental office will have the most up-to-date information about the CGPA requirements for a first-class in your specific B.Tech program.
Don't rely on hearsay or outdated information. Always check official CUSAT resources for the correct and current criteria.
