What did House do for undergraduate?

All I can find about his tertiary education is the institutions (Hopkins and Michigan), but not specifically what he studied for pre-med. I can only speculate he took units of psychology ("if anda want to look at this from a first tahun psych point of view"), organic chem ("more light, lebih oxidation, ring any bells?"), physics (the galvanometer for treating the quad bike burn victim kid), mathematics ("his math sucks" - reference to Dr.Weber's lecture) & biology. Anyone have an insight into this? Thanks.
