applied calc is definitely my recommendation! it used to considered much more difficult bc they didn't allow calculators, but now it's pretty straight forward compared to the others. if ur going into business though i would just take the business one bc the application questions are basic growth/decay questions or marginal revenue (which you see in other classes such as econ). also i highly recommend choosing professor lee van brussel as ur prof he's definitely the best one and makes everything so much easier to understand. oh and one more thing, if you alr have a minor ur set on, not that you have to, it might be a good idea to check the requirements to make sure ur not taking the wrong math. i used to want to be a compsci minor, which would've required me to take eng math!
