Definitely very useful. I do appreciate that there is a rough grade boundary given to give you an idea of how potentially the grade boundaries might look like. It does test every bit of content so that you can identify what you are not fully understanding still and that there is a marking guidance to show you for what steps in your working you get marks for and to show you where you might’ve gone wrong. I like that there is a barcode thag you can also scan to walkthrough the paper with you but I would prefer it as well if the walkthrough videos were also available to people who have not signed up for the plus version. Overall I am happy with the papers and definitely recommend it.
