Sounds like you did a basic pure math curriculum (or minor) at a high-end school, which is probably 4 semesters of extra depth than a computer scientist needs, let alone a programmer. State school applied math / CS does not cover p-adics.
Anyway, part of the value isn't in the material itself, but in the practice of learning hard novel ideas, not just the mechanical fundamentals that you could coast through because you are smart, but then hit a wall when you face hard problems later I life.
