UCI admission revoked?

<p>i just received my second semester grade report and saw that i got a D+ in AP biology, i struggled a lot with the class and i had a 69.8%, and if i had two more points i would have gotten a C-. i e-mailed my teacher to ask if he could just give me a couple of points, would this make a difference? i'm planning on writing the letter that UCI says i need to if i don't hear from him by monday, is there something else, or totally different anyone thinks i should do? thanks in advance for any advice you can give me</p>
