@jdamian123 – you need to log in to CFA Institute’s website to download the mocks. Please go to this link and click download your sample / mock papers now.
It is hard to compare ‘difficulties’ across papers, simply because we are all different – some are better at calculation based questions, some are better at conceptual ones. What we can say is Schweser sharpens your ability at calculations, whilst CFAI mocks (which are actually from CFAI themselves) tends to have more conceptual ones. It’s good practice to do both as it covers your bases for the types of questions.
