I started LSAT preparation with 7Sage back in May, and I started with around -10 to -16 on RC. Having Chinese as my native language, I really coudn't see a way of improving RC since I had serious trouble just to understand the passage itself. 7Sage's low-res and main point method was incredibly helpful for me, and JY gave detailed explanations for each LSAT, which was even more helpful for me since my problem was not being able to comprehend the passages. After bombing my July test, I came back with a 11-point increase to a 173 on August-flex, and eventually ended up with this 176 on November-flex.
I would like to thank 7Sage and JY particularly for making this improvement possible. Lastly, here's a note for all fellow non-native speakers: trust yourself and really try hard for it, we as non-native speakers can achieve a 175+!
I am not sure if you are a Native Chinese speaker. Although I currently reside in the US, I can always share links for several Chinese LSAT discussion groups on wechat or QQ which have a lot of LSAT-flex test takers in Mainland China, if you are a Native Chinese speaker or can at least understand Chinese. Please disregard this reply if you are just living in Mainland China without being a Chinese speaker.
