Impact:
Likelihood:
No input range check for `cutOffScore` in `startSession`
Description: The cutOffScore in startSession function should be between 60 and 100, since it is a 4-week school session.
each student can only get score between 60 and 100, cutOffScore below 60 or above 100 will not make sense.
Impact: This could lead to a situation where the cutOffScore is set to a meaningless value
Recommended Mitigation: add a check that at least one teacher and one student should be present in the school before startSession
function startSession(uint256 _cutOffScore) public onlyPrincipal notYetInSession {
+ require(_cutOffScore > 60 && _cutOffScore <= 100, "Cut off score must be between 60 and 100");
