Physics is challenging, my daughter found a tutor and he really helped her.
But you can also see if there is a list of upper class students that can provide tutoring as well. It doesnt sound like the teacher is a warm fuzzy, maybe dry and brittle? But there are resources and if your having a hard time now, better find resources for tutoring, it can help.
Hey, don't be afraid to ask for help, the place your in is all about learning and that can mean learning to ask for help as well, a skill that can be important when you get to a career.
