Smith is very personal. Classes truly are small with the exception of some 101 classes, and even those have smaller discussion groups that meet on different days. Professors know your name within a few weeks, and encourage students to stop by during office hours or even just to say "hi." Hearing my friends talk about their experiences at larger colleges and universities, I am shocked to hear of classes with 400+ people in them or professors that have no interaction with their students.
Pre-major and major advisers can be a huge help to a student if you choose wisely. I know some students who have been frustrated by advisers that are hard to get in touch with or poorly suited for their field of study, but most students are very satisfied. These advisers help students with the transition into college life, help them choose courses, talk to them about their classes, and generally help their advisees in any way they can.
Class participation is expected at Smith. Though first-years can sometimes be nervous and hesitant to speak up, professors are aware of this and do their best to encourage them. Taking a First-Year Seminar (FYS) can be a huge help to a student, because these classes are small, interesting, and contain only students just entering college. It is easy to make friends in these classes as everyone is essentially in the same boat, and you can help each other transition into college life and academics.
Smith's lack of a core curriculum is a brilliant decision. While friends at other schools are stuck in Calc II and Bio 101 when they know they want to be an art major, I am free to take exactly those classes I want. The only requirement is a writing-intensive course your first year, intended to bring first-years up to college-level writing standards. This can be a difficult level to attain for some students, but making good use of their WI class and the Jacobsen Center will prove invaluable for those students. That said, expanding your academic pursuits is encouraged, and for the Latin Honors program you must take at leasat one course in each of the seven areas of learning. Students are encouraged to take courses outside their majors; classes that interest them whether they put them on a career track or not. Yet, Smith works hard to prepare its students for life after college, frequently bringing in alums to discuss what they have done with their English, Psych, neuroscience majors, etc. The Career Development office also works with students to get them internships, jobs, or just to give advice.
