The "전기기능사 필기 합격앱" is a free Android application developed by 문풀24, designed to assist users in passing the electrician qualification written exam. This app features practice questions based on the latest KEC (Korean Electrical Installation Regulations) revisions presented in two formats: single-question mode and test-paper mode. Users have the option to check answers only when needed, promoting effective learning by encouraging problem-solving without immediate feedback.

With a robust scoring function, users can assess their progress by checking answers midway or reviewing correct and incorrect responses to identify and improve on weaker areas. The app aims to support users in achieving success in their qualification exams.
