More exams
While we're still flogging this almost dead horse, I'll note that (it's not exactly comparable, for lots of reasons, such as foreign students, an apples of exams to an oranges of students, etc) the proportion of firsts awarded by British universities has risen by 4.2% on average every year since 1994/1995, slightly higher than the 3.9% a year increase in A-grade A-levels.
