I agree. Essays are simply too subjective. With AQA in particular, the mark a student receives is a lottery. As many others have said, superb linguists with excellent grammar, wide vocabulary and real fluency often perform worse than much poorer classmates. There are far too many marks for content. Employers don't want - and the country does not need - linguists who write self indulgent essays on "how pop music is a reflection of my personality" or other such nonsense. It is also a national disgrace that at A2 a candidate can write an essay on a topic that the examiner knows nothing about.
