make it clear homie, how many terms your college offers. if you take
fall and winter (which most schools have, running from aug/sept to
march/april) sem classes, doesn't matter if you take or drop the spring
and summer classes as they lie in normal vacation period anyways.
however, if fall and spring are the two main semesters (instead of fall
and winter), and you plan to skip spring, then need to take summer term.

my best advice, go to int'l student office...they know a lot more than any of us here do.
