I'm not sure how, but what I do know is that schools do not know if you tested with accommodations. I think there was a lawsuit about it, but not since around 2015 have schools been notified of who had accommodations on the LSAT. Not just that but they can't know... like LSAC cannot disclose that to them (and I'm 100% sure of that because I also have this accommodation).

Hello! Interested in being added for the August lsat :)
