all subjects will have revised subject content which will be used for all GCSEs in that subject - in most instances this will be produced by the Department for Education
a new grading scale from 9 to 1
non-exam assessment will only be used where knowledge, skills and understanding cannot be tested validly in an exam; this means the proportion of non-exam assessment has been reduced in a number of subjects
tiering will only be used when a single exam cannot assess students across the full ability range in a way that enables them all to demonstrate their knowledge, skills and understanding; this means fewer subjects will now use tiering
November exams are only available in Maths and English language, and only for students who were 16 or over on the preceding 31 August; all other exams will take place in the summer
