Considering how few practice questions are out there, I've decided to make some of my own, based on the new spec questions from the specimen papers.
Here is the first batch of OCR Paper 1 type questions (but applicable for other exam boards' practice, of course). Here is the second batch, concentrating on the new style process flowchart questions: pdf.
And now - batches of paper 2 style questions, the first batch....
But this last one for this exam season is all original work.
