History Classes

I’m currently a freshman, and I plan on taking many classes through my Highschool Life, because I’m confident in my skill to keep up with them. For those who are able to answer my question, I am wondering whether I should take EU or US history first or at the same time? Note, both classes are AP. I was also planning on taking World History depending on certain circumstances. Thank you.

The order does not matter. Just don’t take them at the same tine.
