You may like to create a set of Flashcards to help you to revise the first terms work. I have started one set here: Unit 1: Cells in Action Flashcards
Go to Free Online Flashcards and register as a new user. Use the glossary in the back of your text book to list the new words from each chapter and their definitions. You can use the flashcards as a quiz or for revision. Limit yourself to 10 to 20 cards per set.
