True. An index will help you locate information in your materials during an open book test.

The index is usually found at the end of a book. An index is an alphabetical list of names, subjects, etc. with references to the places they occur. Since you can look up a word in the index and find the page number where it is talked about, it will be easier to find the answer than paging through the book to find the answer.
