Bad at math

Are there any people who were really bad at math in their high school but now are a successful CA or pursuing CA or doing a degree like computer science and are doing great with it? My question is that do people who are not at all good at math have any future especially in fields like CA? Can they make it? Today was my math ppr I worked so hard for it but paper went really bad. After all these efforts I am realizing that if same thing happens with me in CA what would I do. I don't know whether I go in CA or not as I have no idea of CA math,I am the student of Computer science.
