Hi there :) Ya I felt the same way as you about most of my pre-req's that was until I took Anatomy. I loved it but man it was so much info that I really got overwhelmed and then there was the lab class with real cadavers(not that a dead body bothered me) The formaldehyde was terrible! I nearly passed out every time they brought the bodies out to study and started spraying them with that gross chemical. You're probably smarter than the average I would think if you're feeling under challenged and there's nothing wrong with that. You should be proud of yourself! Maybe you'll find some other classes to bring the challenge back into your mind. Anyway that's just my thoughts. Keep up the good work :)
