Since some controlled assessments have multiple tasks within them, (eg my ocr ICT gcse has 2 different controlled assessments within the course, but 4 tasks to choose from for each coursework) and since only one set of grade boundaries are posted each year for the coursework, is it safe to assume that each one has the same amount of raw marks to get an a*, a, b etc? I just dont understand how they could have different coursework tasks with the same grade boundaries, since there will be differences in difficulty between them
