This may explain what happened to me. Of the various standardized tests that I have taken in life (SAT in 8th grade, SHSAT, PSAT, SAT, ACT, LSAT, GMAT), the LSAT is the only one that I did not score in the 99th percentile on, and its logic games section was my weakest. I have never had any test prep training of any kind other than taking old exams; if I had taken an LSAT class perhaps I might have approached the section differently.
