We strongly recommend that students who have no chemistry background or who have not taken chemistry for a long time take Chem 110 before enrolling in the general chemistry series(Chem 142-152-162)

We also recommend that students in the organic chemistry series take their organic labs at a later quarter. Specifically, Chem 241, while it can be taken concurrently with Chem 238, we suggest that Chem 241 should be taken AFTER Chem 238, perhaps concurrently with Chem 239.
