Learn the four common subjects and five elective subjects for both Type 1 and Type 2 exams with 900 questions. Includes explanations, review, and analysis.
This is a practice question app designed to help you easily continue studying for the Occupational Environment Measurement Specialist Examination on your smartphone. It covers both the Type 1 and Type 2 examinations and includes 900 practice questions based on the publicly available exam outline, scope, and past question trends. No login or account creation is required. You can tackle one question at a time during your commute, school breaks, or other short periods of time. The common subjects are: General Occupational Health, Occupational Health Laws and Regulations, Design and Sampling, and An Overview of Analysis. For Type 1, you can also study five additional elective subjects: Organic Solvents, Mineral Dust, Specific Chemical Substances, Metals, and Radioactive Substances. You select either Type 1 or Type 2 initially, and can change it later in the settings screen. For Type 2, the display switches between the home and analysis screens, focusing on the four common subjects; for Type 1, it switches between the four common subjects and the five elective subjects. In the question settings, you can select the subjects you want to study and engage in short practice sessions of 10 or 20 questions. This app offers a comprehensive 40-question practice session covering the four common subjects, a 20-question practice session focusing on the elective subjects for the first-class exam, and a mode that allows you to select all questions within your chosen range. The comprehensive practice session is not intended to be a direct replica of the official exam, but rather a learning function designed to check your understanding across multiple subjects. For each question, you can check your correct/incorrect answer and key points immediately after answering. The premium version includes detailed explanations of background knowledge and decision-making points, as well as the reasons for each of the five answer choices. Instead of simply memorizing the correct answer, you can learn by organizing similar systems and terminology differences, and the reasons for incorrect answers. The answer choices are rearranged for each practice session, maintaining the correspondence between the correct answer and the explanation for each choice. Incorrect answers and learning history are recorded on your device, allowing you to prioritize reviewing your mistakes. The analysis screen allows you to check your subject-specific correct answer rate and learning progress according to your exam category. By identifying your weak subjects and using them in subsequent practice sessions, you can create a learning and review cycle. The app also supports consecutive learning days and standard, large, and extra-large font size settings. The free version allows you to access a selection of questions from each subject, answer and correct/incorrect judgment, key point explanations, learning records, and features that prioritize incorrect answers. By watching a video ad via a single button on the question settings screen, you can add up to 5 questions per ad, up to 3 times a day. The questions are automatically selected from the subject with the lowest available question count, and the added questions are added to the regular subject-specific question count. The added questions remain on your device for repeated study. The premium version is a one-time purchase, not a monthly subscription. Purchasing the premium version grants continued access to all 900 questions, detailed explanations, answer-by-answer explanations, a difficulty question mode, comprehensive practice, a full question mode, and ad-free viewing. If you have already purchased the premium version, you can restore your purchase information from the settings screen. Only if the restoration target cannot be found or the restoration fails will you be able to view the minimum information necessary for support.
