Khan Academy

Before I started school, I was really stumped about the math I learned last year. So I tried to find a way to make me understand the math. Khan Academy has made me understand the lessons in my math class. So thank you, Sal Khan and the team at Khan Academy, for making me good at math.

Great app

Great app for reviewing, studying, or post-academic learning. My one complaint is, since it focuses on more specific subjects it lacks ones such as foreign languages.
