<p>As for your question about taking Bio lab+ Intro to business, while it's completely your call, I think that you'd be better off doing your earlier choice of Chem+ Econ. Macro is an important pre-req for so many classes, and so many majors require it. Intro to Business isn't required for any of the majors or minors, not even the "entrepreneurship and management" minor (it is an elective you can take to fulfill the minor's requirements, but it's not required, if I'm understanding correctly). Plus, it's a lot harder to make up the 1 year of gen chem if you skip it than it is to make up the 1 year of bio requirement. That's my 2 cents.</p>
