Prep for Redesigned AP European History Course

Hello everyone. I wanted to know what are the best prep books for the redesigned AP Euro course are and how good the Princeton Review and 5 Steps to a 5 for this year are. I also wanted to know if the 550 Questions from the Princeton Review and 500 Questions from 5 Steps to a 5 are any good for practice for this year’s test. In addition, has anyone found any practice tests/questions resembling this year’s redesigned course?

Apparently it is a lot like APUSH. My teacher said to go on the college board website and look at essay questions from that.

Thank you!
