I am a current first-semester freshman at the University of Southern California, majoring in human biology. I just switched my major from Chemistry to Human Biology. Although I am only a freshman, I am extremely stressed about my grades and GPA already. I have never been a bad student (all A's in high school). However, for some reason, I am feeling like I am failing already. I am worried that I am going to get a low first semester GPA with a miserable science GPA. Currently, I believe I will get a C in calculus and a B+ or A- in General Chemistry. I know it is still early, but I am wondering if there is any hope. I did leave school for two weeks this semester due to a family emergency, so I know my next semester grades will definitely be better, but I am still not happy.
