@premed-molecule I'm in the same boat, been averaging around ~494/5. I thought about rescheduling but honestly, it doesn't give you much time, maybe the chance to take another FL or 2. If you don't have work or classes to think about and you're feeling really anxious and worried, go for it, it might not make a huge difference in the end but having that peace of mind, rather than a 'I should have done x' is worth it.
Personally, I can't switch because classes start for me and it would be too much but If I didn't have that in the way I would.
I know that may not be really that helpful, but I think it really comes down to what will make you feel the most prepared and least anxious because realistically that extra week isn't going to make you magically conquer a bunch of content but it could do a lot for you mentally.
