Classes next year?

So I’m a sophomore and I signed up to take 4 APs next year. I’m taking AP Chemistry, AP Stats, APUSH, and AP Euro. Does anyone have any tips for these classes? I really want to do well and ge 5s. I’m feeling confident about Chemistry because I’ve had high A’s both semesters and it’s my favorite class plus I’m studying for the June Subject test now. APUSH at my school is allegedly really easy so I’m really just concerned about the exam. I don’t know about AP Stats and Euro but I have had the teacher for Euro before and I like her. Any tips or suggestions would be great thanks.
