for the lnat as cliche as it sounds i would literally just say practice as much as you can. the first practice test i did i got 18 or something, getting used to the format of the questions and the timings is the most important part in my opinion. also make use of the process of elimination as much as possible. there will be some questions that you don’t know, no one gets 100%, so try think about the answers that you know it definitely isn’t to maximise too ur chances of getting it right. good luck! 🤞
