Hi Caitlyn,
It certainly did take a lot of work to become a scientist. I (and other scientists) studied
a lot of science and math in school. Other subjects, especially reading and writing, are important too.
I went to college and majored in physics and then to graduate
school for another six years studying some more and doing research with
my professors. By the time you are in graduate school, though, you are
also working doing science research and often teaching - it is
not all classes.
cheers,
Terry
