Guessing Strategy and Probability Tables

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.

 A# 869 482 429 1780
 A% 18.7% 19.5% 20.0% 19.2%
 B# 964 523 441 1928
 B% 20.7% 21.1% 20.6% 20.8%
 C# 947 487 416 1850
 C% 20.4% 19.7% 19.4% 20.0%
 D# 983 528 422 1933
 D% 21.2% 21.3% 19.7% 20.9%
 E# 884 457 434 1775
 E% 19.0% 18.4% 20.3% 19.2%

All Answer Choices June 1991 - November 2018*

The table above documents the frequency with which each answer choice appeared as a percentage of all LSAT answer choices between June 1991 and November 2018 inclusive. If history holds, you would typically be best served on the test as a whole by always guessing answer choice (D). Do not choose random answer choices; do not put in a pattern such as A-B-C-D-E etcetera. Although guessing answer choice (D) does not guarantee you will get the questions correct, statistically speaking guessing answer choice (D) gives you a slightly better chance of answering correctly than guessing randomly.

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 (D), and in the Logic Games section you should guess (A).

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.
