<p>bluebayou - I don’t think any econ classes specifically require math 8, but phase 2 said the econ 21 prof said she was using math 11 in her class, and math 11 is a combination of math 8 PLUS math 13. I find it hard to believe this is true since, as you imply, neither of those classes is a prereq, and there are LOTS of econ majors who do not have a math background beyond basic calc. But that is what she says the prof was saying. In fact, if you had to take math 3, 8 and 13 before you take econ 21, the majority of students wouldn’t be able to take econ 21 until second year, and many first years take it.</p>
