Do not guess randomly!Because the LSAT does not assess a scoring penalty for incorrect answer choices, you should always guess on every question that you cannot complete during the allotted time. However, because some answer choices are historically more likely to occur than others, you should not guess randomly. The following tables summarize which answer choices have occurred most frequently over the years.
LSAT Answer Choice Probabilities
All Answer Choices June 1991 - November 2019*
Last Five Answer Choices Per Section June 1991 - November 2019*
These statistics do not include any unreleased LSAT administrations.
As the second table indicates, if you cannot finish the final questions in a section, in the Logical Reasoning section you should always guess answer choice (E). In the Reading Comprehension section you should always guess answer choice (B), and in the Logic Games section you should guess (A). This is especially the case because the answers at the end of sections are not independent of each other.
Please keep in mind that the strategies discussed above hold only for pure guessing, and are based on past answer choice frequencies. If you are attempting to choose between two answer choices, do not choose solely on the basis of statistics alone!
On a related note, if you are a strong test taker who correctly answers most questions but occasionally does not finish a section, quickly review the answer choices you have previously selected and use the answer that appears least as your guessing answer choice. For example, if you have completed twenty questions in a section, and your answer sheet contains a majority of (A)s, (B)s, (C)s, and (E)s, guess answer choice (D) for all of the remaining questions to get the percentage of each response as close to 20% as possible.
