<p>Lets say that the professor allowed both classes to take at them same semester (so no prereq of 101), would I have a hard time understanding 102 ? Even if I briefly skim through 101 book beforehand?</p>
<p>I think they're just different: microeconomics and macroeconomics, but check on that. I haven't taken either at Michigan, but I have credit for 102 and not 101.</p>
<p>Yeah, they are related, but different. If I understand correctly, one examines how the marketplace in general acts, and the other how a specific segment of the marketplace will act (I'm taking the micro course, but the area is hardly my forte). I almost took the two courses this summer at the community college (admissions adviser said not to kill myself and only take one). But it clearly is possible to take both at the same time.</p>
<p>you won't have a hard time understanding 102 at all.
i actually took 102 before i took 101 and did just fine.
i wouldn't recommend taking them both at the same time too. it's possible, but it can get pretty annoying.</p>
<p>Also, similar classes usually have their exams on the same day/time. for example, calc 1-4 usually have their exams on the same day, same time. If you intend on taking econ 101 and 102, beware of scheduling conflicts, they can be a real pain in the ass</p>
<p>The ONLY thing you need in 101 that's useful for 102: supply and demand curves and how they shift (cause and effect).</p>
