<p>Ok, so 18.01 and 18.02 are actually two completely different classes… 18.01 is single variable calculus, and 18.02 is multi variable calculus. As such, they will be designated differently on your transcript. Maybe you’re thinking of 18.01 vs 18.014/3/whatever. I’m pretty sure those actually show up differently on a transcript.</p>
<p>As for physics, 8.01x isn’t offered anymore. Instead we have 8.01t (which is the TEAL version of physics that most people take), 8.01L (a longer version of 8.01, covering the same material but taking an extra 4 weeks and finishing at the end of IAP. This class is geared towards people with weaker backgrounds in physics / calculus), or 8.012 (also known as “physics for masochists”). There’s also 8.011, which is for people who failed 8.01 in the fall.</p>
<p>And HASS-D classes… they’re just messed up. Basically, don’t worry about that quote. What they’re trying to say is that you probably don’t have experience in that particular field (for example people taking 24.900 have probably never taken a linguistics class before). This is because more advanced classes aren’t allowed to carry HASS-D credit. But there’s nothing stopping somebody who does have experience from taking a HASS-D class in that field. Also, many people take a HASS-D class, get interested in the subject, and then turn that into their HASS concentration.</p>
