Anecdotal evidence is probably not the best to go off of in this case. The LNAT is an aptitude test, meaning there’s only so much preparation you can do. The most important thing you should be doing is identifying your weaknesses and learning from past mistakes. Nobody can guarantee that they’ll achieve the score they want on the day, but you can better prepare yourself by continuing with your practice. Arbitio is designed to be significantly harder than the real test, which is probably why the average LNAT score of Arbitio users is significantly higher than the scores they average on Arbitio.
