Whether or not it would be too hard depends on what else you are doing in the semester. I know for a fact it would be too much for me right now since I am working 45hrs a week. If you have a lot of time to donate to your studies, you should be fine. I have a friend who took Organic I, Bio 2, A&P II, Calc 3, and Physics 1 all together 😱 and got an A in all but Calc 3... It's possible depending on the time you have to put into it.
Analytical Chemistry was not too bad for me. I studied less than 3 hrs a week and passed with an A...But that's just what works for me. Going into Organic, I'm prepared to study study study..lol
