Not enough time? ABSOLUTELY NOT! Study Abroad excursions have been given me invaluable experiences. Last summer, I did the part of my university's humanities requirements in the rainforest of brazil.
I hate the idea that some people think of premeds, that we are in a hurry or something. What are you in a hurry for? I, for example, have taken 12-16 credits a semester (mind you i did not come to college with any AP credits or anything either) and can graduate in 3.5 years (why? because of the study abroad trip that I did in the summer!).
However, I've decided to extend that period another year and get another degree and study abroad in greece... in fact, i'm leaving sept 10th, and i'm going for an academic year. I'll be studying the language, medical ethics, economics, and basically be having a good time.
In case you're wondering, i'm taking the mcat this august and i'm going to apply from abroad next year.
Although, I readily admit a study abroad for an academic year is extreme, with regards to shorter programs (i.e. 6 weeks in the summer, or even semester trips), you'll NEVER have those experiences again. DO IT!
They are so much fun. More importantly, you learn so much. They're GREAT for your resume too.... i'm sure my medical related studies in a country like greece will make my application unique... for example
good luck
