So I have been studying for a few mmonths and just finished the core curriculum and I was wondering whether I should use all of the preptests or not. I have considered that I may have to take the LSAT a second time and was wondering whether I should leave a few of the preptests in pristine condiditon for potential later studying? for people who have taken a second LSAT what did you do and what would you recomend in studying for the first one and potentially for a second one
