https://www.tes.com/news/school-news/breaking-news/second-alleged-edexcel-a-level-paper-leak-being-investigated-time-itsThe Edexcel C3 exam (20th June 2017) was leaked prior to the exam and the C4 exam paper (23rd June 2017) has also been leaked. This gives particular students an unfair advantage, as they are better prepared for the examination! This will therefore result in extremely high grade boundaries, which are not fair to student who did not cheat. There should be low grade boundaries to cater for the students who did not cheat or a retake!
