Interesting. A pre-u second grade will be awarded more points than one of the new A*s at A level. Meanwhile the points awarded for the IB diploma will be reduced. Clearly UCAS are pushing the Pre-U while quietly trying to disuade centres from doing the IB.
I'm not sure what the hidden agenda is here, but there clearly is one. Possibly the elitist educational establishment fear the international nature of the IB or specifically that the exams are set and marked outside of the UK.
