I finished my first year at university, my GPA is a lackluster 3.26 GPA. I'm doing a dual degree in mathematics and physics, but that's not important. My grades in physics/math classes were pretty good, A's and a B, but my gen eds really brought me down. No room for excuses, grad schools won't accept those. We recently changed our grading to include +/- grading. This was a god send for me, in my head. I calculated that if I take 100 more hours achieving a 4.2 (A+) in each class, my gpa will raise to 3.9. If I continue on for 40 more hours, this could go up to 4.0. An A+ in every class wouldn't be that difficult seeing as I understand how college works now, how serious I should take classes, and the classes I am taking are math and physics classes. Assuming I achieve this, conduct research as an undergrad, do well on the GRE, and have recommendation letters, is it impossible to get into grad school for math or physics?
