Is Foundation right for your child?
Questions parents ask
Are these real OCR past papers?
No. They are brand-new mock papers written in the OCR style, with the same number of papers, marks, timings and question style as the real OCR GCSE Combined Science exam. Because they are new, your child cannot have seen the questions before, which makes them a fair test. We are not connected to OCR.
How many mock papers do I get?
There are 13 complete sets, A to M. Each set has 6 papers, so that is 78 full papers in total. You can buy one paper (£6), one complete set (£19.99), or several sets.
How is it marked?
Questions with one right answer are marked instantly. Longer written answers come with the mark scheme, level descriptors and a model answer, so your child (or you) can mark them the way an examiner would.
Will my child get a predicted grade?
Yes. The final mark is set against recent OCR grade boundaries to give a predicted grade from 1 to 9. It is a guide to where your child is now, not a promise of the final result.
