I took Organic Chemistry 1 this last semester (with the lab) and received a D in the lecture component and a C- in the lab. I am re-registered for the lecture, but am wondering if it is really necessary to re-take the lab. While I understand re-taking it and getting any grade above the C- would be good, I'm wondering if I can focus all of my attention on getting a much better grade in the lecture and then doing well in the Organic Chemistry 2 lecture/lab, or if that would hinder my application prospects down the line.
