<p>you know you can always google the numbers with the word MIT.
"6.001 MIT" will give you the actual name of the class.</p>
<p>technically, offers of sophomore standing are given out without any reference to a strict minimum number of credits, but yes, approximately 96-100 is where you'll need to be.</p>
<p>you are not <em>required</em> to take a HASS every semester; you need to take 8 before you graduate, however, and so taking one each term is a good idea both from a mental health and a fulfilling requirements standpoint. i took two my second term, and am only taking a seminar this term, so i'm neither ahead nor behind...tho i need to find another interesting HASS-D, and pull together a concentration. most people will try to keep the 1/term thing going, but if you hit a rough term where you're just too hosed (or picked the wrong HASS) it's ok to push one or two extra into your last year, when you're basically taking electives and writing your thesis anyway.</p>
<p>of the people i know taking/have taken unified, they usually take at least one or two other classes, one probably being a HASS. unified is 16.01/16.02, tho it does hose more than its share of 24 units.</p>
<p>how do we remember the numbers? same way anyone remembers names of buildings or anything else; use them enough, and they stick in your head. significant subsets of the population can't name any major numbers except their own and those that're GIRs, and some not even that. anyone's confused, they just ask :)</p>
