AP Euro vs. AP World and prep books

I am planning to take either AP Euro or AP World history and I cannot choose one. what test would you recommend and why? And what would be easier to get 5? Also, recommend prep book for both AP World and AP Euro

  • My school does not have classes for both APs, so I am going to self-study. Also, next year I am taking AP Art History, AP Calculus BC, AP psychology with either AP world or AP Euro.

ACT Preparation Yes.
