<p>1 MIT credit =14 hours over the semester which is approximately 1 hour per week so 3 MIT credits is roughly equal to 1 normal credit hour. A normal course load at MIT is 48-54 credits which would correspond to 16-18 credits elsewhere implying my conversion is perhaps slightly generous to MIT students but not significantly so. I’m pretty sure more than 40 students per semester [which is 1% of MIT’s student body by the way] take six or seven classes per semester although I don’t have exact data on that.</p>
