I know we're not supposed to discuss the exams, so I'll keep this as generic as possbile... On Day 1, did anyone else think it unfair that what was being asked / not asked in respect of data was completely 'out of character' compared to past papers? Again, I don't want to be too specific. I think I wasted time 'doing stuff' with the data because it wasn't 100% clear whether it was necessary. I believe a big change in style of question should be made much more explicit in the exam paper's wording. Perhaps though that was just me!
I totally agree it was difficult to gauge what they wanted. I found the first paper very difficult and didn't not what automated checks to use for the model.
