> …I couldn't really find a listing of how big the courses are time-wise.

I spent about an hour a day and it projected a course end date of about two months away. (When you commit to an XP daily pace, it estimates the completion date for the course you selected.) Most courses seem to need 30-90+ hours of study, but it will vary by subject and student since the placement test may put you ahead of or behind others.

> Also did you find it doable to keep up with the daily workload?

No. I set an XP daily pace I felt comfortable with (I think 40XP?), saw the projected end date was far further than I had hoped, then increased my daily pace commitment but couldn't match that consistently due in part to the compounding gripes I mentioned in my parent comment and — frankly — my own lack of motivation.

To stick with MathAcademy or any learning program it's better to have strong motivation in the form of a concrete goal you are working towards. I didn't have a strong sense of that — only a much woolier, "I think a stronger maths foundation would unlock more for me as a software engineer", which is the kind of goal that makes quitting too easy.

If I were to subscribe to MA again I'd first clearly define a goal, like being able to write an AI or game engine physics library from scratch (and then also a strong reason why those things feel important to me, like getting a job in the field or whatever). But I've since moved on to learn other things (design, drawing, painting) and find the motivation flowing much more naturally there. Partly that's because the positive feedback loop flows better for me with art than with maths (the progress week-to-week is highly visual!) but also because I'm working toward a more strongly defined goal.
