Last semester I enrolled in a class, and before starting the class, I called the school to drop it off becase I was already enrolled in two more classes and It was too much for me. I spoke to NORA the advisor from MDC, and i was told that the class was going to be dropped. Apparently, they did not dropped me from that class and i received an F as a grade. I need a 1 page letter for my Financial Aid explaining what happened, and why I need to obtain financial aid for my future classes.
