<p>Forgiven, 401 is supposed to be the hardest of the econ major REQUIRED courses. So it’s a good indicator that shows whether you will be successful as an econ major, but there will be harder electives for those who have passed that step. Some of the 400-level electives, including 409 (game theory) and 418 (business cycles), will probably be the toughest.</p>
<p>But 401 is still tough I heard. And you need to know a lot of math concepts.</p>
