What makes the difference between a "good" exam essay and an "excellent" one?

In both AS and A2 papers, a good exam essay will be characterised by a competent understanding of the key points in the chosen texts, as well as a good overall answer to the question. The analysis is likely to be secure, with an appreciation of relevant context and critical background. The argument will be clear and developed.An excellent answer, which may receive grades equivalent to the level of A at AS and A/A* at A2 level, generally meets the following criteria. The answer will be detailed and exploratory, whilst always answering the question set. The response might challenge the assertions of the question as its basis of forming an argument. The analysis of the text(s) will be probing, developed and insightful. Its focus will be extremely clear, and the line of argument will be tightly controlled throughout the essay. The essay will appreciate and interpret some critical debate. The essay will use contextual information as a means to strengthen the argument and the essay as a whole. The answer will usually have a sense of flair and the argument will be very convincing.
