Prepare by practicing with official LNAT practice tests available on their website, reading complex argumentative texts from newspapers like The Guardian, The Economist, or academic journals to improve comprehension speed and critical thinking. Focus on identifying arguments, assumptions, logical flaws, and conclusions in passages, and practice under timed conditions to build speed since time management is crucial. For Section B essays, practice writing clear, balanced arguments on ethical, political, and social topics within 40 minutes, and consider doing 2-3 months of regular preparation rather than cramming, as reasoning skills develop gradually.
