As for the LNAT essay:
I got a UCL and Durham offers so I guess it was decent enough.
I just searched up the recommended structure and tried sticking to it.
1. introduction (how you understand the question, define key terms, thesis)
2. paragraphs 1 and 2 (state a point, explain, link to the thesis)
3. paragraph 3 (state a counter argument, explain why you disagree, state a point which you link to the thesis)
Some other advice when it comes to the essay:
-connect points logically, make sure the “cause and effect” is visible in every argument
-don’t waffle as the time is very limited. state your points as concisely as possible.
-make the language academic, but natural enough. Do not try to sound too smart on purpose as it might end up being too much. Language is important (so double check for errors and clarity), but your style doesn’t have to be very flowery
-you don’t need real life examples
