It is normal. You may need to relearn what you have completely forgotten. I try to integrate my CS education in my normal software engineering work. The work is high level, not a lot of opportunity to use theory of computer architecture or operating systems, but I'm still writing programs. This means lessons from algorithms and functional programming are relevant. Organizing code using this theory has not only retained the college lessons but reinforced them. My advice is to use the tools from your education when you can, and they will only become stronger when you do.
