I'd be thrilled to have you take the [edit: edX] course with me if you're interested. If you think it's too basic, then I'd recommend the book i linked above. I skimmed it and it looks very good. Also has great reviews. Let me know if you register for the class!
I just registered. I think it will help to go through the basics again just to make sure I'm not missing anything.
I'm also taking a database class offline here, but I should have plenty of time to work on linear algebra.
For reasons mentioned in So8res article as well as for other reasons: studying with a partner can be very good. In November, Adele_L had posted an article for people wanting to find a study partner. It got 17 comments, but only 1 since November 16th. So I thought we (I) should make a monthly thread on this instead of constantly going back to an old article which people might (seem to) forget about. If people seem to agree with that, I will make a post about it every month.
So if you're looking for a study partner for an online course or reading a manual (whether it's in the MIRI course list or not) tell others in the comment section.
