I'd suggest Photoreading both the questions first. Photoread the reference books and essays book.
Use the books with questions for activiation. The idea of the questions books is so that you can do self test to see where your weak areas are. Weed out those you know, do the problems and find the answers to those you don't by superreading and dipping the relevant book/s. This way you minimise the time on stuff you already know and focus on what you still need to learn.
