Abstract

This paper presents an analysis of how well three artificial intelligence chatbots: Copilot, ChatGPT, and GPT-4, perform when answering questions from standardized tests, mainly the Graduate Record Examination (GRE). A total of 137 questions with different forms of quantitative reasoning and 157 questions with verbal categories were used to assess the chatbot’s capabilities. This paper presents the performance of each chatbot across various skills and styles tested in the exam. The proficiency of the chatbots in addressing image-based questions is also explored, and the uncertainty level of each chatbot is illustrated. The results show varying degrees of success among the chatbots. ChatGPT primarily makes arithmetic errors, whereas the highest percentage of errors made by Copilot and GPT-4 are conceptual. However, GPT-4 exhibited the highest success rates, particularly in tasks involving complex language understanding and image-based questions. Results highlight the ability of these chatbots in helping examinees to pass the GRE with a high score, which encourages the use of them in test preparation. The results also show the importance of preventing access to similar chatbots when tests are conducted online, such as during the COVID-19 pandemic, to ensure a fair environment for all test takers competing for higher education opportunities.
