About this app

For the Air Pollution Control Engineer written exam, the process of identifying and reviewing your weaknesses is more important than simply solving a large number of problems.

The Air Pollution Control Engineer written exam preparation app is designed to allow you to solve self-produced questions across four subjects and to repeatedly study questions you got wrong or those you tend to forget. You can check your progress and correct answer rates for each subject, and immediately find the questions to review and the chapters you are weak in.

[Key Features]

1,000+ Self-Produced Questions, Full Range of 4 Subjects

Study the four written subjects: Air Environment Management, Combustion Engineering, Air Pollution Control Technology, and Air Pollution Process Testing Standards. The questions and answer choices are created in-house; we do not restore or include actual past exam questions.

Problem Solving by Subject and Chapter, and Resuming Study

Select the subjects and chapters you wish to study to solve the problems. You can check the total number of questions, the number of solutions, the correct answer rate, and your progress, and resume your study from where you left off.

Detailed Explanations

Check the basis for the correct answer and related concepts for each question. You can review the decision-making process and easily confusing points together, rather than just memorizing the answers.

FSRS Smart Review

Adjust your review timing based on your learning status for each question. You can gather the questions to review today and set the daily review limit.

Incorrect Answer Notes, Questions to Review, Memos, and Review Records

Gather incorrect answers, questions you were unsure about, and questions saved for re-examination in one place. Filter by subject and solution history, sort by importance, and manage your personal memos and the number of times you have solved each question.

Weakness Heatmap

Check the correct answer rate by subject and unit using colors and symbols. You can identify weak areas based on ranges of less than 40%, 40–60%, and over 60%, and navigate to the solutions for those corresponding units.

Practical Mock Exams

Solve a total of 80 questions across 4 subjects within 120 minutes, structured to match the format of the written exam. Check results based on a 40% passing rate for each subject and a 60% overall average, and record your number of attempts and highest score.

Personalized Learning Recommendations

Recommends the next problems to solve based on your solution history and subject-specific accuracy rates. Check the estimated study time and the reason for the recommendation, and start a short study session immediately.

Learning Statistics and Continuous Learning
