What the difference between organic chemistry lab 1 and 2? I have to take orgo 2 lab, but I haven't taken the 1st one. I have taken the class portion of both orgo 1 and 2. The lab is "only" 1 credit and lasts 4 hours once a week. There is one written and practical exam at the end of the semester, along with a lab notebook. It seems like "all" I need to do is do well on the lab reports and do the experiments. ??? Is orgo 2 lab hard?? I'm nervous!!!!
