 ## Abstract
-```
-Nearly all jurisdictions in the United States require a professional license exam, commonly referred to as 
-“the Bar Exam,” as a precondition for law practice. To even sit for the exam, most jurisdictions require
-that an applicant completes at least seven years of post-secondary education, including three years at an 
-accredited law school. In addition, most test-takers also undergo weeks to months of further, exam-specific 
-preparation. Despite this significant investment of time and capital, approximately one in five test-takers 
-still score under the rate required to pass the exam on their first try. In the face of a complex task that
-requires such depth of knowledge, what, then, should we expect of the state of the art in “AI?” In this 
-research, we document our experimental evaluation of the performance of OpenAI’s text-davinci-003 model, 
-often-referred to as GPT-3.5, on the multistate multiple choice (MBE) section of the exam. While we find no
-benefit in fine-tuning over GPT-3.5’s zero-shot performance at the scale of our training data, we do find that
-hyperparameter optimization and prompt engineering positively impacted GPT-3.5’s zero-shot performance. For
-best prompt and parameters, GPT-3.5 achieves a headline correct rate of 50.3% on a complete NCBE MBE 
-practice exam, significantly in excess of the 25% baseline guessing rate, and performs at a passing rate 
-for both Evidence and Torts. GPT-3.5’s ranking of responses is also highly correlated with correctness; 
-its top two and top three choices are correct 71% and 88% of the time, respectively, indicating very strong
-non-entailment performance. While our ability to interpret these results is limited by nascent scientific 
-understanding of LLMs and the proprietary nature of GPT, we believe that these results strongly suggest that
-an LLM will pass the MBE component of the Bar Exam in the near future.
