So it's my junior year in High School and it's my first year I'm enrolled in AP classes (APUSH & APLANG). Anyways, my question is that, I have purchased an AP Review book for APUSH (Barrons 2nd edition redesigned for 2014-2015) and frankly, I have no idea how to use it. Currently, I've been using it for homework and to study for tests by reviewing some material in it, but other than that I kind of just carry it around because I feel like I'll use it, but I end up not. Is there any tips on how to use one effectively? Also, since the APUSH ap exam is redesigned, are there any tips you guys can help me better prepare for the exam? Thanks!
