Biology major -fall 2018 schedule

I just changed my major from nursing to biology and I am gonna start by sophomore year, the classes im taking are I think going to be too hard but the thing is im done with my gen Eds because of concurrent enrollment and AP courses. I also took bio 1 and elementary chem because it was just needed for my nursing major. and I took AP calc and AP bio in high school but I’ve never taken a physics course before.
Im taking ;
evolution diversity of life
calc 1
gen chem 1 with lab
physics 1
is this too much too tackle my sophmore year because I got a B- in elementary chem because I didn’t know how to study btw
