Here is a series of short youtube lectures on linear algebra by the wonderful math channel 3Blue1Brown.
See here for handwritten notes from section/office hours/review sessions/other.
See here for a short writeup on change of basis notation. Note that this was written for 33A, so I do not mention abstract vector spaces.
