Is this higher or foundation?
This is a combined paper for higher and foundation students. You can achieve grades 1 – 9 on this paper, so it is suitable for all. Grades are moderated against the average result to give the most accurate indication of your performance. You can look at – How is this paper marked? for more information.
How is this paper marked?
This paper is automatically marked to determine which questions were answered correctly.
Your grade is determined using a Z-Score moderation system. Your GCSE exams are also moderated comparably so that the difficulty of papers is taken into account.
Roughly, this works by calculating your overall percentage and comparing it to the average percentage and the standard deviation. This means that for harder papers you need fewer points to get the same grade as you would for an easier paper.
As more students attempt the paper, the average score and standard deviation more accurately represent the difficulty of the paper and the grades become more accurate.
Making these papers and the marking system took considerable effort so if you found them helpful for your revision, please show your appreciation by rating the page.
