When Admissions Tutors read your LNAT essay, they want to see three things: a clear argument; supported and developed by evidence or logic; written in an interesting and engaging way. Tutors know that this won't be the best essay you've ever written. They know that you only have 40 minutes to respond to an unseen question. What they want to know is whether or not you have potential. You need to prepare in a way that best demonstrates that potential. I would advise that you read lots of newspaper editorials and opinion pieces in the run up to the LNAT. Think about what argument they are developing, whether that argument is clear, whether the conclusions they make flow from the body of the argument. Try and summarise their argument into a sentence. After doing this a few times, try it yourself. Get an essay question from your friends, teachers or family members and give yourself 40 minutes to write an argument in response to that essay. Afterwards, analyse it just as you have been analysing the editorials and give it a mark. Do this a number of times until you feel confident enough to complete the LNAT essay.
