A handy idea
Use the Five Finger Test to help you decide if a book is too hard for you to read. Open your book to any page. Hold up five fingers on one hand. Begin reading at the top of the page. Put down a finger each time you stumble over a word or come to a word you do not know. If you can get to the bottom of the page and still have at least one finger up, this book has passed the Five Finger Test.
