Greetings.I am writing a petition for AQA to lower the grade boundaries for Unit 2 of physics.The paper was extremely hard compared to previous years and their past papers.Furthermore,it featured a question about "brown dwarfs" which are not part of the specification.Therefore,i,and the whole nation,are requesting AQA to lower the grade boundaries for Physics P2 due to these reasons,plus in Biology Unit 1 ,questions not releated to the specifications were asked(independent company) plus in biology unit 2,a question about "picograms" were asked yet they were not in the specification.Every mark matters,and we want AQA to lower the grade boundaries due to these impossible to know(in regards to the specification) questions.
