Summer before freshman year: Chemistry and humanities classes, work
Summer before sophomore year: Econ and humanities class, EMT class, work full time in toll booth so I got some time to study on the job
This summer: Biochem (6-week) and study for MCAT, work 1 shift a week, take MCAT before fall semester, possibly try to get some more non-clinical volunteering hours if I don't feel overwhelmed.
