> "as a non-English student attending a university in the UK I could easily ask questions in a language the professor could not understand, on forums he doesn't know exist" Yeah, that's not a great idea. It's generally pretty straightforward to tell, especially for CS (more so than mathematics, but the same principles apply). I once had a not-so-bright student IM'ing someone in Chinese asking for a solution right in front of me during office hours. Sure, I can't read Chinese, but I can definitely recognise formulae and code. In a well run class the same person should be grading your homework and exams throughout the semester. I used to find it really obvious when somebody was 'borrowing' something.
