A blue book is a small booklet (with a blue cover) used by students to answer test questions. Inside the cover the booklet pages are line-ruled, like notebook paper. Some professors require students to bring a blank blue book to class when a big test is scheduled.
When you take a blue book test, you put all of your test answers on the booklet pages. You may not be allowed to write on the test itself.
- You can find blue books in your university book store.
- You should always keep a spare blue book in your book bag. You don't want to be stuck without one on test day!
- Blue books usually cost around a dollar.
- Be warned that professors check blue books to make sure that they really are blank!

I bought five blue books at the beginning of the semester. I sure hope I won't need more than that!
