Yes, I remember learning about the different types of agar and media, but my midterm covered those because they were Lab 4 for me. My final is only covering Labs 6-10, but some of those labs did cover biochemical tests, and media to some extent. I didn't have any pictures on the midterm, but maybe I'll see some on the final! And I realize the instructors and vary, so I should take all advice with a grain of salt. I'm going to review the study guide / essay questions, past quizzes, and labs. Thank you for your help regardless of whether my exam is similar to yours or not!
