How to Calculate Your LSAT Scores and Percentile

Score conversion statistics

Getting on , a modern three-section PrepTest, would have resulted in a scaled score of required an incorrect rate of at most:

Note: The score conversion statistics tool above is currently based on the classic four section PrepTest which consisted of approximately 100 questions. Since the modern PrepTests now consists of approximately 75 questions, we are in the process of updating this tool.

How to Calculate Your LSAT Score and Percentile

The term "LSAT score" is ambiguous. That means it has more than one definition. It has three definitions:

1. Raw Score
2. Scaled Score
3. Percentile Rank

Each of these three "scores" are very different from the others. Each serves a different purpose and is meaningful depending on what you're attempting to measure. It's crucial that you understand the difference.

This chart shows you actual conversions between raw score, scaled score, and percentile, including how to scale your raw score into the LSAT score range between 120-180 as well as into an estimated LSAT percentile. Descriptions of the three score types are further down this page.

Note that the raw score is shown here as number of incorrect answers rather than number of correct answers. When studying for the LSAT many students find it useful to think in terms of how many questions you can miss to get a particular LSAT score. For instance, if there are 75 scored questions, and you had a raw score of 64, you would be -11 on that PrepTest.
