Firstly, the Intermediate folder (and the others in that section) is just for polls asking questions, so access is restricted- people can reply in threads, but not set up new ones. It's for practising, not asking questions.
To enter a university in the UK, you would need to have your acdemic qualifications recognised and meet the language standards. There are twoi main tests - Toefl and Ielts - that are used, though some places acccept exams like the Cambridge Advanced. Each university can set its own standards required, so the best thing is to contact individual universities and ask them. It also varies between courses; things like computer programming, where high standards of English are less important, require a score significantly lower than law. What nationality are you? If you are from outside the EU, then, I'm afraid, you'll find that the courses are very expensive, though there are variations in price. EU citizens and EFTA ,members get the same prices as UK citizens.
