<p>150 and 151 is probably the more challenging route. If they gave you credits for 140 just take 141. Most people won’t need calc 3 ever. I know that AP Calc BC is like 141, although 141 is a little bit more challenging. My advise is, don’t over-estimate your mathematical ability before you get here. I thought it was going to be a piece of cake in my first couple of weeks doing math 141 in my first semester because I had already seen a lot of the integration that they were teaching, but it was challenging. I wouldn’t have made it through without the help of my TA. You can always switch in the first couple of weeks. Try 141 first and talk to your prof. I would recommend 141 unless you want to go into something like econometrics or…I don’t even know what kind of science concentration would require calc3.</p>
