Biology Final Exam Review Sheet – Academic

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 remainder of the semester. To get full credit for the review you must answer the questions on a separate piece of paper. It must be handwritten. 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 on the due dates you must turn in this paper. I will record your grade in the checked column on the timeline below. On the last day I will add upall of your daily grades to calculate your final grade on this assignment. On the final day, when grades are recorded, you must have ALL sections. If any sections have been lost then points will be deducted. The answers to this review sheet WILL NOT be accepted after the last unit is due. It is very important that you have the review packet with you and completed on time!!
