I found these excellent resources very useful. I have always considered working through examination type question papers to be the ‘Gold Standard’ of revision work and this collection of questions certainly did all I expected. Thank you, please keep up your valuable work.

i didn't use it

I use my touchscreen foldable laptop and interactive pen to work. like an ipad, but it'd my laptop. I don't have a program that let's me do this the pdf files, so I convert pdfs to work files. I could covert you'd file, because it was locked and needed a password.

Chem paper

Whilst not being accurate in a sense of the questions, the ones on the predicted paper where MUCH harder than the ones on the real one so I felt prepared
