Biology teachers are apathetic about if you learn or not.
They only care about their own personal research.
DO NOT MAJOR IN BIOLOGY AT UNC unless you did private school, a prep program, were the top 5% @ of your High school or if you can study really well to pass AP or IB exams with 4's and higher etc.. the average GPA for a bio major at UNC is a 2.6. this means that you cant qualify for barely any awards, scholarships, or even study abraod opportunities. Dont major in bio if you do not think you can be responsible and teach yourself everything. Tough love...
