Hi - I tried taking some courses as Hunter, but the issues I came across were: 1-The don't (or at least weren't) offering science classes in the evening. 2-Even day-time science classes are almost impossible to get into if you're a non-degree student. I ended up taking Developmental Psych and an English course there, but then I took all of my science pre-reqs (chemistry, A&P I&2, Microbiology) at Borough of Manhattan Community College. I would definitely recommend going to BMCC or another similar 2-year CUNY school that is more accomodating to non-matriculated students who are working fulltime. They offer science courses in the evenings and on weekends. Also, the courses are generally small--no more than 25 students, and I had good experiences with professors over all, with a couple of exceptions. It can still be a bit competitive to get in to classes, but much less so than Hunter where it's nearly impossible unless you're pursuing a degree. I only ever took 1 science course at a time while working fulltime, and found this to be manageable.
