About this app
For the first stage of the Customs Broker exam, it is more important to review necessary content in a timely manner than to solve a large number of problems.
Prepare for the four subjects of Introduction to Customs Law, Trade English, Domestic Consumption Tax Law, and Accounting all in one app. It includes publicly available past exam questions and a question bank organized by unit, along with detailed explanations. Furthermore, FSRS calculates the next review time based on your memory status for each question.
[Key Features]
Full-range learning by subject
Learn the four subjects of Introduction to Customs Law, Trade English, Domestic Consumption Tax Law, and Accounting by dividing them into subjects and units. Progress and correct answer rates are displayed for each unit, allowing you to identify and focus on areas you haven't touched yet or your weak points.
Past Exam Solutions by Session
We have included 9 past exam sessions from the 34th to 42nd rounds (2017–2025) organized by session (Gonggongnuri Type 1). You can select a session to solve the questions in the exact order of the exam papers, or you can select specific subjects to view. Question Bank by Unit and Detailed Explanations
We have included study questions across all units, tailored to the exam scope and 5-option multiple-choice format. To ensure you don't just check the answer and move on, we have explained why that answer is correct and why the other options are incorrect.
Mock Tests
Practice with a mock exam structure consisting of 160 questions to be completed within 160 minutes. You can check your results against the passing criteria of an overall average of 60 points or higher and at least 40 points per subject. After completing the test, you can review your scores by subject and the questions you got wrong all at once.
Initial Diagnosis
Check your current skill level with a brief diagnosis at the start. You can determine which subjects to tackle first before beginning your studies.
Question Search
Enter a word you are curious about into the search bar to find related questions immediately. Since the search is conducted across concepts, questions, and answer choices, it will find the correct answer even if the wording is slightly different.
Selective Study Mode
You can select the scope of questions to solve by subject or unit. Turning on "Start with Unsolved Problems" allows you to continue solving problems you haven't touched yet.
Continue Solving
Your progress is saved even if you exit the app while solving problems. When you return, you can resume your studies from where you left off.

Indicates how many times each problem has been solved. You can continue your review by distinguishing between problems you have reviewed repeatedly and those you are not yet familiar with.
Question Frequency Analysis (Premium)
