I knew before this semester started that would likely be needed. My science gpa needs improvement. I am not in a give up hope situation, it is just discouraging. I know I can get through it plenty of people do.
Definitely. Just spend some time searching on SDN. A LOT of very successful people struggled with orgo.
Your sGPA needs work anyway, so this really isn't going to kill you and there is absolutely no reason to even think about giving up hope because of it, or to even be discouraged. A lot of really smart people get tripped up in orgo.
You are being smart about it by getting in front of it. You very well might find orgo 2 easier, either due to the exposure from orgo 1 or maybe, hopefully, you'll have a better teacher. But, either way, since you are going to need a post bacc anyway, why pile more on by taking biochem simultaneously? My advice would be to take something else where you are guaranteed to get an A in order to get a little head start on the GPA repair.
In fact, if orgo 2 is not co-requisite for biochem, maybe consider dropping orgo 2 and taking biochem. That way, you can begin preparing for the MCAT while doing your post bacc. Orgo 2 is not nearly as important for the MCAT as biochem. In fact, plenty of people take with MCAT without orgo 2. I don't even think it's a prereq at some schools.
