To read or not to read

In your college level English class the students are required to read novels. In order to interpret better, you decide also to read the novels. But you don't have a prep period during which to read. If you read, it would be done on your own time.

On one hand, you've been wanting to read these novels and now have a perfect excuse. On the other hand, shouldn't you be compensated for your prep work? After all, the prep works takes time from family/hobbies/other work.
