Chemistry, and science in general are not my strong points, so I commend you for starters!

I say go for it, you know that it may be very challenging for you, and you can mentally prepare for that in advance. Maybe it would be wise to take a lighter load so you have more time to focus on this one course (if that's possible). Take advantage of the free tutoring if you need it.

What I found was best in my college experiences was to find a buddy in the class (usually the one that was smart and I could understand). These people were often better than tutors simply because they could put things to me in a language I understood rather than technical speak.
