Lots of practice. Contrary to peoples thinking that you cannot prepare for this exam, you most definitely can, provided you have an excellent strategy in place. Initially, I did the 2 mocks and learnt from those mistakes. My essay writing skills were very poor in the sense that I could not structure it well, over time it significantly improved through repeated practice ( 15 essays). I did more mocks and MCQ practice in the last 2 weeks ( best time ) and learnt ALOT of tips. Also did some newspaper reading, but not as much as I wanted to. LNAT is hard need practice. Do the LNAT MOCK in the last week. Goodluck.
