I'm sorry but I can't help but be critical. This seems more like an advertisement for a duolingo-for-math than a serious personal undertaking. I am not sure if this level of proficiency is something you want to boast of at the end of 1000 days of self-directed study, regardless of what level you started at. Do you think you'd be better or worse off with just doing two days a week with a personal tutor?
Also I am fairly certain that not taking a day off has hindered your progress rather than improved it. This is not a productive attitude and ritualizes the study instead of encouraging self-reflection.
Do you actually have any concrete issues with Math Academy, or do just want to bitch?
So tired of posts vaguely criticizing instead of naming any tangible problems.
In what country do you live that a personal tutora two days a week is financial compareable ?!
Your criticism is poorly informed. Math Academy is definitely not a "Duolingo-for-Math". As a platform it's far from perfect, but as a program it's a serious and complete secondary school to undergraduate university math program, with excellent explanations, reinforced by well-thought out exercises. It's definitely competitive with the top-rated math textbooks in each of the areas it covers.
As for the OP "not taking a day off"... for some of us ritualization is productive because it's what we need to stick with a difficult program. Maybe for you that's not the case. To each his own.
(I have my own criticisms of Math Academy: The platform should be more flexible in pacing and allow repeating sections. It should have built-in spaced-repetition features. And the company is uncommunicative and aloof. I'd be willing to overlook most of these faults at a lower price-tag, but for what they charge it really rubs me the wrong way.)
