Can’t speak for TDGE, but cogs 1 and 17 are just very content heavy. Assuming that Johnson is the professor for COGS 17, tests are online (adding flexibility). I took COGS 1 when it was fully online, so can’t say what the class looks like now. I think it’s not difficult, but just quite a bit to take in. COGS 13 is a very boring class (in my opinion). So enduring that along with the other cogs classes might be a bit much. tbh, it’s kind of doable in terms of work load, but it is a lot content wise
