Math Prep for Econ PhD

<p>I'm currently a masters econ student and I have only taken Calc 1 parts A/B in undergrad in 2011, but decided I would like to at least attempt to enter a phD program when I am done. What math courses should I take? I am eligible for part C of single variable at my current school, but not sure if I am prepared for it since it's been a while for me since undergrad math, and I know I forgot trig functions among other topics that I don't use in my econ coursework. </p>

<p>Should I spend a term and retake my original courses? or Possibly do a business calc class as a refresher class for parts A/B?</p>

<p>I only have 3 quarters left of school left so my wishlist is to take 1c asap so I will be eligible to take 2A, Linear Algebra/ODE combo class, and Basic Set Theory/Proofs, but not sure if that's logical or not.</p>

<p>Side note: I can always take linear algebra or ODE at a community college since they have less pre-req requirement, but not sure how admission committees look upon that.</p>

<p>thank you for any feedback :)</p>

<p>I wouldn’t waste time retaking Calc. I’d self study. Use free Khan Academy or maybe there are free courses online. </p>

<p>Thank you ! Any topics you would recommend focusing on? I might go ahead and sit in on a Calc 1B course during summer to help refresh myself without wasting any money so I can start on 1C in fall.</p>

<p>Multi variable calculus, linear algebra, differential equations</p>
