I'd be nervous, too. Our school doesn't allow you to take Orgo and Gen chem simultaneously. Both Gen Chem 1&2 are prereqs for Orgo. With that being said, your first semester looks fine. Your Winter Semester [is this over break or the same as Spring?), not so much. I just think that you have too many science classes. If you can, I'd advise you to at least drop Orgo or Chem (preference to drop orgo first) and take a humanities/english/other class that is considered a general requirement. Take it from me. I took Gen chem and Bio together my freshman year. Granted, a C+ is the avg. for gen chem 1, which is what I ended up getting, and Bio was a B-/C+ avg. I got a C+. BUT, my study schedule was lax, and when I look back on my first year, I didn't really study nearly as much as I did 2nd semester. Both Bio 2 and Chem 2, spef. Chem 2 was supposedly more difficult than Bio/Chem 1. I took bio 2 and Chem 2 second semester and got a B+ and B-, respectively. 🙂 Just don't overdo it. That's a lot of science classes for a freshman, so just take caution. If you start the Winter session and at the beginning feel like it's too overwhelming, drop it before it's too late. Don't let your GPA suffer.
