APUSH and Khan Academy

Hi!
I am a freshmen in high school and I am probably going to take APUSH exam next year (as a Sophomore).
Our school divides APUSH into 2 sections; US Hist 1-H is the first half, taken in Freshmen year, and APUSH-2 is the 2nd part, taken in Sophomore year.

I am currently in US Hist 1-H, and I want to review the information I learned this year in the summer so I don’t forget it.
Is Khan Academy a good way to review for the AP exam? By the way, the book we use is “A People and a Nation - 9th edition.”

Thanks!

Anybody?
