EXAM QUICK REFERENCE

ERE Basic exam quick reference

Six micro and six macro chapters cover the standard introductory range. Chapter 13 handles the true/false and four-choice CBT formats, and chapter 14 is for those who already studied economics at home: the models are known, the Japanese phrasing is not.

Written from the public ERE Basic guide. ERE Basic is distinct from the full ERE used by some graduate programs, and nothing here claims a general written-test waiver.
