Biology 1st Semester Exam Review General Information It will be entirely multiple choice questions. Make sure you answer every question. You may use a note sheet that is one side of 8x11 sheet of paper o This must be handwritten notes and diagrams. NO photocopies are allowed. You must stay in the room for the entire time (no early release and no bathroom breaks) so take care of necessities before you come in. Study tips Be sure you know all of the material on the review. Write information on the topics that are giving you the most difficulty on your notesheet first.
