Summary:

The function does not validate whether the provided cutOffScore is greater than zero. This oversight may allow invalid or meaningless configurations, reducing the reliability of the contract's session logic and fairness for students.

Vulnerability Details:

There is no check to ensure that _cutOffScore > 0, which may allow the principal to initiate a session with an invalid or meaningless threshold, effectively graduating all students unconditionally, or introducing logical errors in future validation logic.

Impact:

Setting a cutOffScore of 0 would automatically qualify every student, regardless of performance.

Logical inconsistency: Future functions that rely on a valid cutOffScore may misbehave.
