UTA Prerequisite Courses

I looked everywhere for a topic on this to no avail, and I'm honestly just looking for a support system. I just started the UTA AO prerequisite courses. I have about 8 prerequisite courses left after I complete this semester. I transferred here from Hill this semester, and as I'm sure you all know, Hill is a community college. Not to knock anyone who goes there, but it was easy peasy compared to this. I'm not even proud of my fantastic GPA anymore, because after being at UTA for three weeks, I feel like I didn't even earn that. I have been in Intro to Nursing and Technical Writing for three weeks now, and where Technical Writing is a piece of cake, Intro to Nursing has been so difficult for me. I feel extremely discouraged, because everyone described this as an "easy" class, and even with all of the studying I've been doing, I've barely been able to maintain a C. Please someone tell me that they empathize with me. I think my friends are getting tired of hearing my breakdowns. :/
