About this app

This learning app contains past questions from the National Examination for Radiological Technologists (the national examination for radiological technologists), covering 17 examinations from the 62nd (2010) to the 78th (2026) examinations, totaling 3,386 questions. All questions include key points and explanations.

The National Examination for Radiological Technologists consists of 200 questions in total, divided into morning and afternoon sessions, each lasting 155 minutes. The scope is broad, ranging from basic medicine to physics, electrical circuits, image engineering, nuclear medicine, radiation therapy, and safety management. Many questions involve interpreting images from a separate booklet, such as MRI, CT, and X-ray. This app can be used by students aiming to become radiological technologists to prepare for the national examination, allowing them to focus on image-based questions and areas of weakness.

■ Features for this Exam
- Practice 508 questions using images from the separate booklet. You can filter by type (MRI, CT, X-ray, ultrasound, circuit diagrams, etc.), and images can be enlarged to full screen by tapping.
- The mock exam consists of 100 questions in the morning and 100 questions in the afternoon, each lasting 155 minutes, just like the actual exam. You can choose which exam sessions to solve or have them randomly arranged.
- If you choose to be exempt from some exam subjects, your daily studies, mock exams, and pass/fail assessment will be structured using only the five subjects that are exempted.
- The pass/fail criterion meter allows you to check how many points you need to reach the total score threshold based on your recent mock exam and practice scores.
- For "Choose 2" questions, select 2 answers just like in the actual exam. The official scoring procedures, such as exclusion from scoring and multiple correct answers, are directly reflected.
