We have produced 4 revision papers A,B,C and D which contain the adapted questions from our adapted C1 papers but with all the questions reshuffled between the papers.
Our questions are carefully based on the original. We change only the numbers in the question in such a way that the solutions still fall out with the same degree of difficulty and number of stages as the original problem.
You get the benefit of redoing and revising similar questions that you may have struggled with earlier.
