I found it difficult enough, but I didn't really know what to expect. As you probably know, it is a written exam so it's much different to all the others. All of my tutorials were cancelled and there is only 1 sample paper in the manual, so this may be why I found it difficult. People who were able to attend tutorials were probably more prepared and had a better understanding of what was expected of them.
I have sat Life & Pensions combined as part of the old course and Investments, Loans & Financial Planning as part of the new course (and due to sit Regulation Saturday week). I found all of the exams fine, with the exception of Financial Planning, while I think it's fair to say the new course is more difficult it is certainely do-able.
