I've you've been out of school for more than, say, five years, it is quite possible that quite a bit of what was taught and covered in college is outdated in today's marketplace. Perhaps for people who went to vocational school, but not for liberal arts and sciences majors. The math behind much of Computer Science, for instance, has been around for decades and it does not change. Sets, hash tables, queues, etc.
