I can help you with AP Stats and AP Psych. I got 5s on both of them.
I didn't take AP economics (either of them), but I did take macroeconomics and microeconomics my first semester in college. Don't remember much though, but you could still hit me up with questions if you need to.
5 APs isn't that bad. You just have to space out your time. I took 9 my senior year and got 4s and 5s while still maintaining a social life. It's all about planning!
