Most of them yeah. I at least read the beginning of the ones I didn't like... to find out that I didn't like them. Can't remember which ones I didn't like though.
I will say that I loved The Road though. So much. I ended up writing the greatest essay on it, too.
In highschool, teachers assign books to their classes to study and write essays, tests, exams, etc on. Did you read these books, or did you read the summaries of each chapter on Google?
