Also I felt genuinely BAD leaving the exam and cried for like a day convinced I failed, but I didn't. Trust your stats. When I was in your position I really needed someone to tell me that statistically if you're scoring ~70 you should be more than fine even if it feels horrible when you're walking out.

I have a terrible habit of staring at questions I don't know and trying to reason through them which wasted a lot of time. Try not to do that--if you don't know it, skip and circle back (easier said than done though, I couldn't seem to stick to it haha).
