How can I revise maths with no past papers?

To be honest the questions don't change that much, there're probably some extra things you need to know which you can use the books.

So do you think the style of questions would be very similar to the old ones and that they would prepare me well enough for the exams?

So I’m in year 12 and I do maths as one of my a levels. This is the first year of the new maths a level and the exams are no longer modular; they’re linear. This means that there are no past papers from previous years and there is no way of knowing what the papers will be like. Maths always came naturally to me so I usually just revised by doing past papers but since this is not an option in this case how else could I revise it so I can still get an A? I know that I’ll just have to practise a lot of questions from the text book but will this be enough? How is everyone else in the same situation revising? I’m on OCR, btw.
