Honors Chemistry sound more impressive than regular Chemistry, but not worth it in this case. Pre-Med, Pre-Pharm, or not, I recommend staying away for the sake of your GPA. Apparently, he's retiring after this year, though, so you might be much better off next Fall! I have a friend that made an A, so it's not impossible- I just feel that most students would be better off learning AND having the grade to show for it, rather than just learning.
