If they wanted to slack off senior year, they should have taken a less rigourous course load. Perish the thought!
Agree with those who say…don’t slack off. That is the best “safe harbor”.
The other thing…rescission is one issue, but some kids are awarded merit scholarships based on their GPA…those kids need to check to see if their senioritis might end up losing them thousands of dollars, or prevent them from attending a college entirely due to the costs without that aid.
