"Break Days" Before Exam

I think as we get closer to exams, the anxiety really ramps up so break days are important. I'm just curious how in the last week or two you handle those? My test is next Wednesday and I've been working all week, so I was planning to take a day off Sunday to reset ("bored" day), do a full day Monday, then do a quick half day on Tuesday.

My scores on COMSAEs and TrueLearn aren't amazing and I would likely benefit from postponing my exam, but unfortunately that's not possible given my rotation schedule/school requirements/chosen specialty requirements. So right now it's a mix of anxiety and fatigue.

Tl:dr Is taking a day off three days before the exam an awful idea?
