Oh my god, you got a 5 on the US History test? That one was hard. Random facts are not my strong point.
I got a 2 on that one from just taking the class and looking at a few notes the night before. I really did not study like you did. That’s very intense. Did you have any extracurriculars to juggle?
But anyway, good job! Congrats!
How to pass my AP tests
It made me 
"With fourteen tests in three years, high school slowly became torture. Luckily I passed all of them."
How I did it: Studying and personal sacrifices. Could I go out and party with my friends every single weekend? Pssht, no. Could I sleep on school nights? No. Could I have a lunch period? Phaha, nope. It was hell.
My life consisted of a constant stream of coffee/espresso running through my veins, with 24+ hours of sleep each weekend.
Also, I knew when to take a break. The night before the US History test, I went two states away for a concert. Cramming at that point was nearly pointless - luckily I still pulled a five. Your scores are pretty much set a few weeks before the test, there's no way to go from a one to a five in a week.
When I sat down for the Human Geography test, which I didn't even take a class in, I skimmed the review book the night before. It seemed easy, but I managed to get a three only because I didn't take the time to learn what the course was about.
I studied a lot, but then again, I did have outside knowledge. That's what really allowed me to do it.
Lessons & tips: Don't give up! As long as it's possible, do it.
Resources: Countless AP review books saved me. Really.
