Getting more hours of sleep or studying?

CFA Level III
#1

I’m getting 4.5 - 5 hrs of each a day.

If you don’t know the information required to pass, then less sleep because you NEED the info to pass.

If you have the basic info and you’re polishing up minor details, then sleep. Can’t think unless you sleep.

#3

But if you don’t sleep then your brain turns to mush and it’s tough to study, even with caffeine. Need to be efficient…4.5 is not enough sleep. You don’t need to know everything to pass. Get some rest.
