I'd say you have a good chance, but that totally depends on you. On my last DEP meeting, we had the fortune of listening to a guest speaker (who so happened to be an officer EM). Anyhow, he was saying how he wasn't all that great in school, but he did give it his all. Do not be discouraged if at first you are not picked up for officer! The ensign that spoke to us told us that he made that mistake and wasn't picked up until a few years later. You got to keep trying, you can do it. He also spoke of how he made officer (simple stuff on how you are tested, but if you know your stuff, . That when they review your application, they go a lot by recommendations of your superiors and by the fact that even if you weren't able to complete a task, that you did give it your ALL, without excuses. I'd say you can do it if you put your heart and soul into what you want. Good luck.
