If your purpose in reading the book is to pass the test, then you can probably formulate questions that you'll be asked, or are likely to be asked, based on a) previous exams from this professor, and b) this book.
You might want to characterise the questions you've had from this teacher before.
Some general questions, which can't hurt:
Who are the characters? What are the important scenes? Are there any wacky plot twists? Is there a passage that "rings true"? What is the most intense scene in this book? What is the most memorable? Is there some great dialog?
There might also be meta-questions (depending on what level you're at), such as, "why is this book important?"
Finally, I've found that reading a book the "old fashioned way" once I've photoread makes the reading go much faster, and easier to remember.
Good luck!
For activation I would suggest that you focus on say the characters for then setting, plot location, theme, Symbolism, Philosophy, Imagry etc. If you superread and dip with those things in mind you'll probably be able to finish the book in a lot less time. You could probably find the answers to those questions in an hour. Once you have them you have the option of doing a rapid read. You'll probably spend a lot less time on it by first superreading and dipping for an hour discovering those details.
My questions article explains what to look for in the way of theme, symbolism etc. If you haven't got a copy feel free to email me for one.
