After taking an astronomy course in college, I decided I want to major in physics with a concentration in astronomy. My current major has nothing to do with science or mathematics. This summer I took a physics class and I'm currently still taking Calc 1. I got an A in physics, but so far in calculus I have done HORRIBLE on all three of my exams, there's only one more week of class left, and I don't think it's possible for me to pass even if I miraculously got a 100% on the final. I study so hard for the exams but I failed miserably every time. So my question is, should I retake Calc 1 this fall where I have more time to absorb the material than I do during summer, or should I just give up on this whole thing? Thanks, and please no rude answers.
