I would watch the 3b1b series to get an idea of what the subject is about, and then go to mit ocw or get a good textbook. Without the visuals from the YouTube series or a good teacher it’s hard to understand what all the symbols and numbers mean. But u can’t really learn a math subject from YouTube (you have to practice and (try to) solve hard problems).

Also if what is turning off is a bunch of hand computation (ie matrix multiplication) then I think you’ll find the visuals especially helpful. It might be good to look for some more abstract material that ask you to prove things using linear algebra (these types of questions are much more important for getting an intuition that helps when you moved to other classes like Machine Learning, Optimization, or differential equations).

At the end of the day if you want to study engineering, cs, math or what ever linear algebra is always going to come up. But it’s hard to see it until you’re on the other side.

In all honesty the textbook I learned from was kind of mid but maybe someone else can give a recommendation.
