Ouch--- I had just written a whole pile and it dissapeared!! NO, one doesnt have to do the NAS 161/162 route, there are other ways of getting the required classes. It is prob the shortest method though (less credits)
Another route is BIO 205 and BIO 141/142. I took bio 141/142, THEN took Bio 205 and Bio 101 in the same semester, a bit backwards,lol And I took Chem 101 prior to taking BIO 205, and I belive I had to contact he school to take BIO 205---not sure who I contacted to get approval, think it was Mrs V, and she was obviously ok with it.
I went with the "BIO" over the "NAS" classes as I was told they would transfer a lot easier to other schools
than "NAS" classes would. No clue if that is true or not!!!
Ur best bet is to contact student services or the 1st yr dean, thats what I did,lol
