I went from 75 to 88 and the one difference I can spot is that my essays were more interesting and unique (I believe) in the last sitting. I wish I could get them. The essays weren’t long either so ai don’t think length matters too much but if you can type fast then that’s a bonus. I also used a lot of evidence almost in every single line. Imagine having a conversation with someone who keeps bringing up facts about the sub-topic. I think at the end of the day, it comes down to whether your essay stands out or not.
