alm2020 - as was mentioned, this will be explained to you in great detail at orientation but in the mean time, I’d advise you to check out these three links:
1st - Distribution Requirements for anyone in LSA - you’ll want to understand the types of general requirements as you can take course in your 1st semester to fill these and won’t be wasting credits
2nd - LSA Course Guide - explore Fall '16 courses that will fill these requirements
3rd - info for prospective Poly Sci majors.
