They are getting rid of a lot of CW/practicals and replacing it with exams so if you are good at exams then youll do well but if you always did better on CW you may not do as well as you could of done the years before
Overall i'd assume there would be about the same grade results. Despite the fact there will be less CW/Practicals where people less good with exams can make up marks... it does allow for you to spend more time working on exam technique and to be taught content.
