This September I will be going back to school after being away for 3-4 years. When I was going before, I took a class in point-set topology. I passed the class, but only with a 53. This wasn't for lack of ability, but for a lack of motivation. I dropped out of school after that semester and did other things with my life. Now that I am more mature, I know that I want to go back to continue my math studies and I will be fully devoted this time. My question to you all is: A 53 in topology looks bad. At my school, you are allowed to retake a course in which you already have the credit for, provided the reason is because you need a higher mark for entry to a certain program. You are allowed to this once and once only. I am thinking of requesting to retake topology and cite the reason as: "Topology is an important math subject and grad schools would look down on me if I have a low mark in it". I think that reason would work. But is it really important that I retake topology? I have been self-studying it and I feel that I am quite good with it. Nonetheless, should I retake it so that grad schools will see that I got a good mark in it? I think that my new mark would completely overwrite my old mark, making my old mark invisible to anyone looking at my transcript.
