In general, O-chem and a couple other classes that I'm guessing he is currently enrolled like ChEn2001 are designed to show students the type of effort that will be required in upper level classes. If he can master time management required to handle these classes, he should be fine in the last 2-3 years of the program. I can assure your son that the extra effort he puts in compared to his CLA friends will definitely be worth it. Even in this economy most of my classmates and I were able to get full time jobs out of school. I can't say the same for my liberal arts buddies.
Hope this helps. Good luck to your son.
