I've been going through that for a refresher and it's been pretty useful. Not sure I'd rely on it alone for learning calculus, but luckily there are some other really good resources, like:
For Statistics, I've been going through the Duke/Coursera "Statistics with R" sequence, as well as the Johns Hopkins Data Science specialization.
For math higher than Calculus... well, I haven't really gotten there yet, but Gilbert Strang also has a series of lectures on Linear Algebra on Youtube which are very well regarded, from what I've seen. Also, there are Youtube videos on pretty much everything you can think of, all the way up to Abstract Algebra and what-not. How good they are, I cannot say.
For "pre calculus" review stuff, Khan Academy is pretty good.
Some other good resources are the Math Stack Exchange site (note: math.stackexchange.com, not mathoverflow). Homework'ish questions seem to be allowed, although with the usual caveat that you're kinda expected to have at least made some effort before asking.
There are also several sub-reddits dedicated to learning math. I forget what they all are, but look for stuff like
/r/cheatatmath
/r/learnmath
/r/mathhomework
etc.
I think if you just hit /r/math there's a list of such sites in the sidebar.

1. MathBFF's Youtube videos. https://www.youtube.com/user/mathbff
2. Professor Leonard's Youtube videos: https://www.youtube.com/channel/UCoHhuummRZaIVX7bD4t2czg
3. Gilbert Strang's Calculus Lectures: https://www.youtube.com/watch?v=UcWsDwg1XwM&list=PLFW_V3qDH5...
Also, Khan Academy.

For Physics, there are more stackexchange sites, and there are the forums at https://www.physicsforums.com/
