Fitter

Fitter is a learning app that allows you to select past exam questions based on specific criteria and review your solution records and incorrect answers.

You can start mock exams tailored to you by selecting various exam types—such as Civil Service, PSAT, NCS, Korean History, and professional qualifications—and setting the specific exam and number of questions.

You can solve problems and check your score immediately, and review incorrect answers in your error notebook. You can also check your recent exam records and study progress to quickly identify which areas require further study.
