faculty advising program
I chose to come [to Commonwealth] because of the tight-knit community and the challenging academics. During my time here, I've really enjoyed all the close reading I learned from English 9. It's totally changed the way I look at literature. I also love the fact that I can take public transportation to school and around downtown. It gives me so much independence and I absolutely love it.
