I’m a CS undergrad. I know English and French, and it helps when I want to check out what other people think about the puzzles, etc. Currently, my aim is to get better at C++. I just rush through the puzzles and revisit easier ones, when I get stuck. Basically, I’m trying to learn a programming language like if it was a foreign language; through trial and error, with some theory when I have to. I also try other languages as you can see from my achievements, but that’s just to have some fun, it’s better than playing computer games imo.
