<p>When I was writing down my courses as they ask on the supplement, it asked term/block. Well, term made me think of 1st and 2nd semester, but block made me think of what period (i.e.- B1 for your first class on a B-day). Anyone have an answer?</p>
<p>Some schools are on a "block" system - kids take one course at a time for a number of weeks. Then they take the next course and so on. "Period" is not the same as a "block" in the term that it's used on the supplement. The supplement is just giving you the options that may best describe your high school's system.</p>
