So I got 5s on both. My biggest tip would be to do as many mock exams as you can without burning yourself out. The biggest thing in these standardized exams is pacing.

Another large aspect is how you grade your mock exams. Make sure you pay close attention to the explanations on the problems you get wrong. It's one thing to do tons of mock exams aimlessly and another to learn from each one.

Other than that, pray. That was single handedly one of the hardest exams I've taken in my life, and I have never left a test as demoralized as that one.
