I graduated in 1989 from Swarthmore. Many students feel claustrophobic by the end of 4 years at Swarthmore, so your current feeling of constraint will probably get stronger. Despite the train station on campus, it was my experience was like yours: it’s not terribly practical to use. I was very neurotic about my study habits; workaholic. Sweatmore does culturally encourage that orientation, but I also brought to the college. I think that the college is very homogenous and its culture limiting in many ways, and the rigor is over done. Bigger schools have more diversity both cognitively and culturally than Swat. From what you write, I hear that you are inclined to transfer, and I encourage you to explore that desire to transfer. Then explore the idea of staying. compare the two psychological experiences. As long as you have strong grades and can transfer to the schools you listed, I doubt you will regret it. I would not attend Swarthmore if I had a do-over, but given many challenges that I face at the age and stage, that may say more about me than Swarthmore.
