I just got accepted to the college of chemistry and I took a semester of chemisty in my junior year at my local university and got an A. It was a 2 semester class and I sent in a drop form 2 weeks into the semester but as I’m looking at my transcript it never got dropped and I ended with a a D so on my UC application it says I took one semester and got an A and just says I didn’t take the class second semester. Am I done for? Can I call and explain or am I pretty much screwed?
