I'm going to take this exam this month and I have already prepared quite a bit but I'm panicking now because I don't know if I've done enough

It's a general ability kind of test, I have done 17 practice exams so I've done a lot but how can I maximize my potential during those final 5 days?

Also is it worth studying this week? I've been studying for around 5months non stop, I don't wanna burn out
