I was @ 39k and still struggling with 119.
There are some exams that are easier then other (100-120), and a few are definitely power checks. I tried multiple comps found online and most rely on either high bp or spamming tries for perfect set of cir*stances (it took me 600 tries @30-32k to beat 100 lol)
Realistically youll be able to finish through 120 with your sanity intact as you get closer to 40k+
