<p>I got everything I wanted to know from your answer. As you said, the most important thing is to look for credit policy of each university. I’ll also check whether or not universities of my choice usually accepts credits from EPGY, which I’m just taking. I found some other threads about early graduation from MIT or other universities. According to them, some people who don’t major in engineering or pre-med(as you said) can do that. I hope I’d do the same thing as you did if my major, biology, wouldn’t be so time-consuming.</p>
