Tutor app?

[ItsJustDomo]

Are there any free tutoring apps for iPad 2? I could really use the help since I've been piling on classes, mainly online, and my online math class is killing me. I'm one of those people who need to understand things completely or it bugs the heck outta me. Plus I need to bring my grade up, I have all A's except for that class.
Help please.

The "Khan Academy" app is awesome! It has many subjects but they also include many great videos that help out a lot! This app got me through calculus.

I agree about Khan Academy. It is THE best place to go to find self-paced video tutorials. The math topics are extensive, so anyone needing help in math, this is the place to go.
