Tangential to the topic of this post, but how have you found brilliant? I’ve been considering it but don’t know if it’s worth adding another subscription to my monthly spend when I could presumably get a lot of the same knowledge from YouTube (albeit in a less structured way). Any thoughts?

Plus:

Brilliant’s computer science courses cover slightly more than my actual software engineering degree from Aberystwyth university, and their maths courses cover more than I did at A-level.

The various introductions to matrices (in different contexts each time), are better than the introduction I had in my A-levels (with a good teacher!), and I would say they are of comparable goodness to 3blue1brown. Only, all of it is that good.

If you get stuck because a topic assumes knowledge you don’t yet have, they have a course to teach you what you need to learn.

I can’t comment on the levels of Brilliant’s physics, chemistry, or biology as I have only GCSEs in those subjects — but I can say they’re well-described and engaging.

Negatives:

Limited practice materials, e.g. I still suck at probability because I’m not groking the broader implications of their simpler lessons.

This is neat. I was taking a Trigonometry course online. Was great at first but I kept running it references to “as we learned in Algebra or Geometry” Well dang it, I aced trigonometry in college, but apparently I have completely forgotten some basic building blocks. So I need to start back at basic algebra and work my way up to find the missing gaps.

Thanks for replying! Sounds like I should try it out. My maths could use a refresher and I could use an engaging way to learn it. Much appreciated.
