MIT frats/sororities are pretty understanding of the workload, so it's not really hard to "strike the balance" in terms of balancing schoolwork and Greek life. For example, last semester I probably put in (max) an hour per week for AXO. Certain frats might even demand less (the only -mandatory- activities, really, are chapter meetings and house jobs). Of course, if you're on the exec board or active in a committee it might take longer, but still isn't that time consuming (I was also webmaster, and that took maybe 10 minutes a week, if even).

I am impressed, however, that your brother was able to be an intercollegiate athlete as well. I've heard from some friends (mainly in tennis/swimming) that the athletic schedule can be killer.
