Of course, the central point of the A* grade is to distinguish between the good and the very good. However, from the perspective of universities, they need to be able to determine who has achieved the very best grades. That system of grade distinction has already been in place in the IB for the last 30+ years, making it only logical for universities to raise A level offers while keeping IB offers the same. So, the second point of the A* is to make it more comparable to IB and other exam boards.(Original post by hobnob)
Erm, no, it isn't. The point of introducing the A* grade was to counter grade inflation a bit by allowing a distinction between As and very high As. The comparability of IB-points to A-level grades is a separate issue.
