December

Read Chapter 5: Energy, Metabolism, and Enzymes, Chapter 6: Cell Respiration, and Chapter 7: Photosynthesis in the Barron's book. 

DO NOT complete the quizzes after these chapters; these will be completed at a later time. 

Review Chapters 2-4.

Take your first full practice AP exam in this book or from a different source. Time yourself appropriately. You will not do very well because you have only studied about half the material so far, but use this as an opportunity to learn about the structure of the exam and the type of questions asked. Focus on the parts of the exam that you have learned about to be able to gauge your review time.
