I think the main value for me is in the note taking process and seeing the patterns that come up, but it's helpful to have if I need to review or if I get a tutor, as they can review it for patterns in my errors too.

I would use the notes feature on here more often if I could access all the notes in a single tab (like a Notes page under Analytics or something) instead of them embedded in the question only. For now I use a Google Sheets document but it'd be more helpful having the question information right there to see like on here.
