The three things that leap out at me are 1)all year 11s have to do 8 GCSEs of which 5 have to be EBacc subjects, which will be a real struggle for many, 2) no more tiered papers, so one exam for all, so kids for whom a C is a real achievement have to sit a paper which has also to cater for the effortless A*, and 3)only the first attempt at an exam counts for the league tables. This means for a school like ours, where the vast majority of students are middle/low ability, and where we have always let many have a "practice go" early, won't be able to- because the risk to the school is too great.
