Sorry if I misunderstood. I don't think most CS curriculums teach you analyzing programs and writing them efficiently. My data structures and algorithms classes were great but still not enough practical knowledge to implement programs day to day. On top of that, there was practically no code review. I don't think there's enough time for professors and TAs to analyze your code and tell you if this is a good way of doing things or is it clean or will it waste a lot of memory.
