So if I want to get college level math education, then pic rel is all I need, right?

What are the best sites and resources for learning math?
In the past I used KhanAcademy. I tried it again but they've totally changed the website and it's basically unusable garbage now. The videos and exercises are pretty good but it's terribly organized and difficult to navigate, and it looks like it's all geared for young children. Also there's just so much crap. They apparent they've really shifted their focus to quantity over quality.
I'm interested in trigonometry, single and multi-variable calculus, linear algebra, differential equations, abstract algebra, real and complex analysis, number theory. Need something with lots of practice/exercises.

You DID donate to it, right?

>uni was online only for second half of Spring 2020
>online only for summer sessions
>will be online only again for Fall 2020
>no labs
>no in-person teaching
>all courses are online, usually just pre-recorded videos and substitute teacher-style busywork
>I'm paying tens of thousands of dollars for glorified Khan Academy videos
Why is this allowed?

Is this the future of all unis?
