when to take a last full length sample exam

thinking of taking one last full length practice exam. definetely don’t want to do it 2-3 days before the exam to avoid fatigue. with about 5 days to go think its a good idea?

I just finished 1. I have 2 to go in Schweser and then the big dance rehearsal (mock). By now, you should be in marathon shape. I plan on 1 2 days before the exam and then the day before the exam, I’m reviewing the mock.
