<p>I'm currently a graduate econ student and I have taken Calc 1 parts A/B in undergrad in 2011, but want to improve my math skills to apply for a PhD program for Fall 2015. I know I need to at least partially retake those courses to help regain the fundamentals in order to succeed in calc 1C and linear algebra/ODE since I didn't put in the best of effort the first time around. I could technically go straight to 1C but don't want to mess up.</p>
<p>My preferred 3 class path would be Business Calc--->Calc 1C--->Linear Alg/ODE combo course since I am on a quarter system and have 3 terms left in school so this would work out perfectly. But is business calc enough to refresh me? Or should I start from the beginning?</p>
