It appears to be true. I was given a generous offer anyway and the course I hold an offer for was in clearing last year. So that evidence seems to suggest they are quite lenient. But as I think I've said and indeed others have said, it just depends on demand. They want a full course, they want your money. What's slightly worrying, albeit understandable, is that clearing courses can sometimes be only for international students who have to pay more, so I've heard.
