Two. One course must fit the description of Economics 201 (Principles of Microeconomics)
and the other course must fit the course description of Economics 202 (Principles
of Macroeconomics).
Two, but there are conditions: First, upper-division units must be in courses that
clearly fit the course description in the Cal State San Marcos Catalog and satisfy
any conditions or prerequisites. Second, the following courses must be taken at Cal
State San Marcos to receive credit: Economics 301, 302, 303, 441, and 471.
You should enroll in these two courses as soon as possible. Math 132 or 160, in particular,
is a prerequisite for many economics courses and Math 242 is a prerequisite for Economics
471, Econometrics.
Definitely. Suggested math courses include Math 160 (substitute for Math 132), 162,
260, 262, and 374. Please see the chairperson of the department for other suggestions
about preparing for graduate school.
