I'm on about universities where so few actually miss their grades that they won't have places.
With the awarding of predicted grades, virtually all offers will be met. Most universities give out far more offers than they have places. So we'll end up with a situation where the top universities all have to give places to people that have made an offer to and no one will go to the lower ranked institutions. The universities wont be able to cope logistically!
Moreover, there will be a large number of students who will 'take a punt' at going for a better university next year, and they'll be competing with those who have to take exams next year.
