+1. I was excited for it and it sounded nice in theory but in practice it was just too much of a slog for me. I picked it up because I have a non-traditional math background and while I more or less know calc + LA, I do lack fluency with the concepts. Perhaps I am wrong, but at my level I feel that I don't need to go through 10 trivial variations of the same theme and many foundational concepts could be massively condensed. I am instead progressing much faster just picking up a textbook and referring back to precalculus books to fill in holes where needed.
