I am working/living abroad and need to take an accredited course in Multivariable Calculus and Linear Algebra (thank you Econ undergrad for not being enough to get into econ graduate school).
Does anyone have a view on good courses? Thus far, I've found the one hosted by the Stanford Summer program, but it costs over $5k, and one run by a place called Cal Campus, which is significantly cheaper.
Has anyone ever had experience with either of these programs or know of other programs that would work well for Economics Phd programs?
