I took BIO 201 online at PC and in BIO 202 online at PC this semester. Also finishing up BIO 205 at Rio Salado which I started in November (taking the final in 2 weeks). If it was your only course it's probably doable but my 205 course is 16 weeks but I am also taking 5 other classes so in retrospect you could probably do it in 8 weeks. Micro is a lot of information but I'm guessing the PC format may be easier versus other schools
. Can you find the syllabus to see what is required?
