Well...I enrolled for my MBA at a school I like. But they told me I have to take a pre-requisite course for econ since I only passed Micro with a 'C'. I got an 'A' in Macro. However, both of these courses were five years ago...so I don't really remember much about econ. They told me I have two chances at the waiver test...which is free. It's 50 questions, and you have to score 70%. If I fail but score between 60-69% I can take it again within 10 business days. Do any of you know of any good study material? It's probably graduate level econ since the course number is 5620. One book recommended was Essentials of Economics by Bradley Schiller. Anyone have any other material you think would help?
