ChatGPT earned full marks in nine subjects during this year's unified university entrance examinations in Japan. LifePrompt Inc reported that the AI achieved 97 percent accuracy across 15 subjects overall.

The subjects with perfect scores included mathematics, chemistry, informatics, and politics and economy. Performance was lower in Japanese language, where ChatGPT scored 90 percent, reflecting challenges with processing complex text.

Tests were conducted without access to the internet, with the AI relying solely on pre-stored data. Results show that ChatGPT has steadily improved since 2024, outperforming scores required for competitive programmes such as Human Sciences I at the University of Tokyo.
