Biology Final Exam Review Sheet – HONORS The biology final exam consists of 50 multiple choice questions. The questions are grouped into categories. The categories and questions may not appear in the order they were taught in class. Categories include: molecules of life, cell physiology, cell energy, genetics, embryology, and microbiology. The exam makes up 10% of your overall grade. It is very important that you take the final exam seriously! Studying is not an option, it is required. Portions of this review sheet will be due throughout the next few weeks. It will be checked daily. To get full credit for the review you must answer the questions on a separate piece of paper. It must be hand written. Write out detailed answers. Your answers do not have to be in sentences, but they do have to be detailed or you won’t receive full credit! Use your notes and the textbook to answer the questions. When you turn in the questions each day you must turn in this paper. I will record your daily grade in the checked column on the timeline below. The answers to this review sheet WILL NOT be accepted late. It is very important that you have the review packet with you and completed on time!!
