Edx/BUx Introduction to Differential Equations Starts 5/16

That's definitely part of it. Plus, my personal opinion is that the Study.com stuff is pretty lightweight...I don't think it's a good prep for anyone looking for a math degree, where people are going to expect you to...well...'math stuff', as my 8 yr old says. (Where math is, indeed, a verb.) If you like shorter explanations, then the Shaum books, are a lighter approach but have significant numbers of solved problems, or even one of those "365 solved problems in ____" books would give you a better feel than the "mostly words" approach of the Study.com videos.

For folks just needing to whip off a math course, it's fine. To build a deep foundation, not so much.

(Don't get me wrong, I love Study.com...when words are the appropriate medium for the lesson. With math, I feel they need a LOT more numbers and fewer words, both in lessons and in solved-problem examples outside of the videos.) That's just my personal opinion, with a strong preference for 'learning by doing'. YMMV.

ETA - Ideas, if you have an old books shop near you, some of my fave calc books have been from the 1950s-70s, before there was all the super-gimmicky printing, 4-color glossy artwork, etc. Where the pages were mostly numbers/equations, clearly laid out so you could follow the process without all the cutesy stuff, and where text was very crisp, concise, and clear. *Those* were math books. I haven't found a modern math book that I like even a little, in any math subject.

Oh, another resource. MIT's amazing professor, Gilbert Strang, has a bunch of DiffE videos (and at least a text or two) - the videos are very good. (Dr. Strang and Dr. Fowler, previously mentioned for Calc 1 & 2) are the only 2 math professors I'll watch "just because" I want to wallow in math a while. Dr. Strang has some that are just the math side, and he has some that add in MATLAB implementation with Cleve Moler of MathWorks (for anyone thinking of an engineering degree...I'm pretty sure that AMU/APU have switched from LabView over to MATLAB recently, and the Boston engineering schools all go heavy on the MATLAB from year 1).

There have been a few others, including myself, who have found their non-math courses to be lightweight. People feel like they're learning, but they don't know what they're not learning.
