Khan goes up to Calc II (If Calc II involves Taylor Series. Basically almost everything before Multivariable Calc). It contains Diff EQ, intro stats and probability, as well as Linear Algebra but he doesn't have anything on the Junior Undergraduate level. I'm not sure of his plans to expand to it either. From videos I've seen, I'm given to understand he wants to do more topics on an intro level rather than delving into the deep dark depths of say, Fourier Transformation.

If you need the basics though, Khan is your man. You'll learn how entertaining the phrase "switch to magenta" is as well.
