What I wish I learnt in my computer science classes?
I have attended two different universities in France. I got my bachelor degree in Computer Science in a tiny university close to my hometown. Then, I moved to a bigger city to study in an engineering school, and graduate in "Computer Science: Software and Networks". I also spent two semesters at Laval University, in French-Canada, which was a really great experience.
After two years working as a software engineer, there is a lot of things I wish I had learned at school and some other less.
Note: I have also been doing an internship in a UC university where I have seen how different studies were in the US, so this applies only to french/european school in a certain limit.
