I am not a practicing biologist, but have a degree in Aquatic Biology (Fisheries). When I came out of college in 98 I would have been looking at a minimum of 3-5 years of part-time, seasonal employment at <$15/hr. You should contact somebody in the field you want to be in and get some real world info on employment opportunity. My original department head blew smoke up my a$$ about how great the job market was when I entered the program. Regarding education, it sounds like you'll get by, might struggle a little through some chemistry and math, but if you enjoy the core classes, you should get a decent gpa. Best of luck.
