EEB 2245: Each half of the course counts for 50% of your lecture grade. Your grade in the first half of the course will be based on your performance on two lecture exams (for a total of 200 points). Your grade in the second half of the course will be based on your performance on three lecture exams (180 points total) and weekly, short on-line quizzes (20 points) (for a total of 200 points). However, your grade for Exams1–4 will be dropped. Please note: because you are allowed to drop one of these grades, we will not give make-up exams.
This schedule is subject to change. Check regularly for updates!
