The main difference between the ChemE program here and any other major (here or most likely elsewhere) is the “pillar” structure that they take to approach their core classes. Instead of having 2-3 core classes per term with some additional side classes (labs, electives) ChemE has a single “pillar” class which counts for 6 credits (instead of 3) and cover a lot of material. I can’t remember how often they meet but I believe it is 2-3 times a week for up to 3 hours at a time. These are huge group classes which are taken with your entire class within the department (except for sophomore year which is too big to fit in a room, so two sections are offered but taught at the exact same time).
Beyond that, specific questions you have would probably help. My boyfriend just graduated from the ChemE program and could give insight into his experience, just as @amandakayak mentioned with her son.
