Article-format lessons import directly; video lessons come in via their YouTube versions.
Its article-format lessons import cleanly on their own, while video lessons need the YouTube route since the site itself doesn't host a transcript. That combination makes it a solid base for a beginner-level study notebook in math or science, K-12 through early college. Depth stops well short of college-level rigor, so it's the wrong source once a notebook needs to go past the fundamentals.

Lecture notes and open textbooks are the highest signal-to-noise sources for studying — often better than the slides you were given.
