About this app

For the first stage of the Certified Tax Accountant exam, reviewing necessary content in a timely manner is more important than solving a large number of problems.

Prepare for four subjects—Public Finance, Introduction to Tax Law, Introduction to Accounting, and Commercial Law—all in one app. It includes self-produced questions and detailed explanations for each subject, and FSRS calculates the next review time based on your memory status for each question.

[Key Features]

Self-produced Questions and Detailed Explanations

We provide study questions tailored to the scope of the first stage exam as defined by the Enforcement Decree of the Certified Tax Accountant Act and the five-option multiple-choice format. You can review key concepts and the rationale for judgment together, rather than just checking the correct answers.

Analysis of Question Frequency

We have categorized publicly available exam questions by subject and chapter to determine which chapters appear most frequently. For Introduction to Tax Law, the Income Tax Act and Corporate Tax Act have a high weight, while the Act on the Punishment of Tax Offenses has a low weight. Use this as a standard to decide where to spend your limited time.

FSRS Smart Review

It widens the intervals between questions you remember well and shows you frequently missed questions again sooner. You can study at the point when your memory starts to fade, without having to manually select the questions to review today.

**Study by Subject**
Study Public Finance, Introduction to Tax Law, Introduction to Accounting, and Commercial Law by dividing them into subjects and chapters. You can select and focus on questions you haven't solved yet and your weak chapters.

**Mock Exams**
Practice with the actual exam format, solving 160 questions 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 in each subject.

**Preparation for Failing Grades**
For the first stage of the Certified Tax Accountant exam, failing any single subject results in disqualification regardless of the average score. The system displays the correct answer rate for each subject separately, allowing you to identify the risk zones for failing in advance.

**Incorrect Answer Notes and Weakness Analysis**
It automatically collects incorrect questions and displays the correct answer rate by chapter. You can identify your weak areas and immediately proceed to studying the corresponding chapters.

**Learning Records**
Check your daily problem count, correct answer rate, and consecutive study days. You can manage the amount of study accumulated during your commute and spare time at a glance.

Offline Study
You can solve problems even without an internet connection. You can maintain your study flow even while on the go.

Device Synchronization
Once you log in, you can continue viewing the same study records across multiple devices.
