If you liked the video consider subscribing! - For AP students, semester 1 starts at 0:00 and semester 2 starts at 17:21
I compiled two files from tornato7 (one from YouTube & one from soundcloud) then I sped them up but kept the pitch the same in an attempt to keep the voice sounding as natural as possible. Credit goes to him.

Use this video if you're in a rush studying for the AP test, SAT subject test, high school final, etc.

This video is a great summary of everything that has happened in U.S. history. Watch it a few times and take notes while listening if you want the best grade possible (it's fast).

I hope it helps!
