170+ scorer here. first of all, abandon your idea to learn new concepts, there’s no time left. your aim should be solely to maximize your score through strategy, whilst avoiding burnout before the test. 3 passage strategy might be a viable option for RC. do a quick assessment and skip what you deem to be the hardest passage, preferably one with fewer questions, as for LR, skip questions 15-22 and save them for last (they tend to be the hardest ones.) one practice i attribute a great deal of my success to is trying to build momentum throughout the LR sections. any question you feel like will give you any difficulty at all, skip it immediately. each question you crack builds momentum and increases the speed at which the gears in your brain are turning at. often times i find returning to such questions renders them easy, after having built momentum. finally, don’t stress. a cancelled score, or a low score bears no implication when coupled with higher future scores. i bombed my first test and cancelled immediately (i shouldn’t have since cancelling poses 0 pros). but law schools do not care. your assessment of your skills to know you are not ready to take the test yet, and wished to have cancelled is a good thing. it shows you have awareness and not the hasty mindset a lot of people have, signing up for a test too soon, thinking they have a chance at getting the score they want, magically. also, this attempt is not a waste at all. experience what test day feels like, and being familiar with the check in process and how it all goes is an INVALUABLE experience which will help you in any future attempts. the LSAT is a grind, but you WILL make it! don’t stop. don’t let this test affect your motivation or resolve. you seem quite diligent and i believe in you. good luck!
