Below is a set of Objectives and Study Exercises to focus your studying for the Biology 107
midterm. This is NOT ALL that you need to review but does outline major concepts that were
focused on in the course.
Try not to look at your notes when filling this out! These questions are NOT representative of
exam-style questions – they are very broad and vague – use them to get you thinking not just
Good luck studying and, as always, contact me if you have any questions.
