Academics is highly volatile. It depends on the department, the course, the professor, the students in the class, and you.
The good part is that there is the option of doing a dual degree, which involves two bachelors (not just two majors), and I know in some universities this is not possible or very hard to do (like Stanford). There are many schools and a wide variety of majors, as well as the option of doing an individualized major, and changing majors is quite easy.
In the College, or SAS, there are a lot of general requirements, which is good if you are only getting one major because you can explore and expand; but they get very annoying when you are trying to complete the requirements for a minor, and another major in another school. The administration is terrible too. The psychology major is a joke, but I guess that's true everywhere. In general, being in SAS is not that strenuous in terms of work, even if you take 150{4a082faed443b016e84c6ea63012b481c58f64867aa2dc62fff66e22ad7dff6c} workload (6 credits).
The College has been for me a terrible experience, and moreso because I can contrast it directly with Engineering. The administrators in the College don't motivate you, quite the opposite: they get pissed if you try to do more than you should. The first time I took 6 credits (the limit is 5) my advisor was very angry and condescening. In Engineering, it is more common to take more credits. In Engineering, for any type of request, you just fill out a petition and turn it in. In the college, it is a whole process to fill out any sort of petition; you have to go talk to an advisor first, who will supposedly 'advise' you, when you just actually waste 1 hour.
Engineering, or SEAS, has more specific requirements because it is obviously a more specialized major. This is good since you end up actually learning something useful. You also have to take a lot of social sciences and humanities, giving you freedom to explore other areas, and not just science.
The environment in Engineering is a LOT more welcoming than in the College. SEAS organizes semesterly events, the advisors in general are better, you get to know people better, and there is a sense of community.
Students are very competitive. Grading is usually on a curve, meaning the average is a B/B+, so you only have to do better than everyone else to get an A, which can be easy or hard (depends on the course). I've taken very hard courses and done well, very easy courses and done poorly.
I feel that in general professors don't care about you. They don't know your name, and don't care to know. There are some rare ones that know who you are, nod their head when they pass you in the hall, but beyond that do not really venture further.
