Each administered LSAT typically contains approximately 100 or 101 questions, and Each LSAT score is based on the total number of questions a test taker correctly answers, a total commonly known as the raw score.

After arriving at the raw score, a unique Score Conversion Chart is used for each LSAT to convert the raw score into a scaled LSAT score.

Since June 1991, the LSAT has utilized a 120 to 180 scoring scale, with 120 being the lowest possible score and 180 being the highest possible score.

Although the number of questions per test has remained relatively constant over the years, the logical difficulty of each test has varied.

Compare selected scores from the charts for the following two tests:
