As the parent of a recent grad, I found Swat students to be no more stressed than at other schools. My description of Swat students is focused, or curious. They work a lot, but they seem to enjoy it more than many other students. We hosted several for weekends and holidays, and they were often working. Not because they were stressed, but because when they had some time they wanted to get back into work. I watched one student do calligraphy for an entire Thanksgiving weekend. He was having a blast…doing work for a class.
As for the food, there are other on-campus and off-campus options that “round out” the options. You won’t go hungry…and the new dining hall is nice.
