Before I knew about photoreading, I once read a first year linear algebra book, as a review for another course. What I did was just read all the statements of the theorems and corollaries. I didn't read the proofs or the examples. I found it very easy to see and understand every thing in the course.
That being said, many math courses aren't really about the subject content. They are about learning the form of the proof. I've yet to see a math course with more than 4 basic proof / tricks. So find those and learn them and you are set.
PR and the right purpose can make passing course a lot easier. At least from hind sight I believe so.
That's not your synoptic oooops syntopic ready list you were looking for. Try Schaum's notes and other summaries. Just hit the library and you'll find at least a half dozen authors writing on each course. For under standing I would recommend the older books. Those published 50 or more years ago. The courses were thought differently then. My experience is they are less rigorous, meaning less theorem proof stepping, but are an easier source to learn the subject.
Good luck and happy learning,

P.S. I won't be back until after the retreat... black out here and the computer is going back off after this post.
