Getting a 4.0 in high school is do-able. Getting a 4.0 in prereqs- do-able but challenging Graduating from 4yr BSN with 4.0- incredibly challenging. It depends on the school, the professors, if they curve, if you have responsibilities outside of school. The only person I know who graduated with 3.9 lived at home, had no bills, and didnt have a job during school. So good luck to you, but don't beat yourself up if you dont stay at the 4.0 mark.
