What kind of student were you academically before nursing school and during nursing school ?

Hi, I'm asking this because I just graduated from high school and I plan on going into nursing school. I was wondering if the people who get in nursing school are all the kind of students who used to be very good in high school or not especially. I'm wondering this because sometimes I feel like I'm not smart enough to get in a program. So were you during high school and nursing school the kind of student to study a ton and always have good grades or not particularly?
