# 간호조무사 - 국가시험 CBT 모의고사 자격증 문제풀이 > We cover the four subjects of the national exam—written and practical—by unit. We identify weak points through error notes and weakness analysis, and guide you to success by asking questions again just when you are about to forget.

This app is not just about increasing the number of questions. It focuses on pinpointing your current weaknesses and retrieving questions you have already solved just before you forget them. Because the cognitive science-based FSRS algorithm analyzes the forgetting curve for each question to automatically determine the optimal review time, you can reduce the leakage at the minimum passing score (40 points) for each subject, allowing you to reliably surpass the passing mark (60 total points) even with the same amount of time invested.

[Key Features]

Full range of 4 subjects including the practical exam · Over 4,300 questions

It contains over 4,300 questions covering all subjects, including Basic Nursing Overview, Public Health Nursing Overview, Introduction to Public Health (including medical laws and regulations), and the practical exam. It was produced in-house to reflect the examination standards of the National Examination Board.

5-option multiple-choice CBT identical to the actual exam

The National Nursing Assistant Exam will switch to a computer-based CBT starting in 2025. Practice exactly as you would in a real exam, reading questions on the screen and selecting from five answer choices.

Detailed Explanations

Each question comes with in-depth, detailed explanations. Instead of just checking your answer and moving on, the app covers key concepts, common pitfalls, comparisons of confusing concepts, and memorization tips for each question.

Learning Tab

This tab is designed for when you want to review concepts first. The four subjects are divided into 131 learning units; within each unit, you read the key concepts and immediately check your understanding with practice problems. The app automatically remembers where you left off, so you simply need to continue reading from where you left off.

Various Solution Modes

You can choose to solve problems by subject or chapter, and your progress and proficiency levels are displayed for each unit. You can start with unsolved problems or gather and focus on your weak chapters.

FSRS Smart Review

The app extends the review interval for questions you answer correctly and quickly shows you the questions you frequently get wrong. You don't need to create a review schedule yourself; the app takes care of the questions you need to review today. Review Notifications

We remind you of review times just when you are about to forget. Daily study reminders and FSRS review timing alerts help maintain your study flow.

Weakness Analysis Heatmap

View correct answer rates by subject and unit at a glance. Visually identify your weak areas and move directly to solving problems in those units.

Review Box

Gather incorrect answers and questions to review in one place. You can leave personal notes for each question, allowing you to review by seeing the reasons for your confusion alongside your organized concepts.

10 Practice Mock Tests

We have prepared 10 practice tests in a comprehensive format of 105 questions across all subjects, identical to the actual exam. Select a test and time yourself to solve the problems; the system automatically grades your score by subject, whether you failed (40 points per subject), and whether you passed (60 points total). It also manages your highest score and test history.

Exam Preparation Checklist

We have compiled the items to bring the day before and the day of the exam, exactly as per the National Examination Board's guidelines for examinees. It helps you ensure you don't miss your ID, exam ticket, or entry time.

**Learning Statistics and Continuous Study**
Check your daily problem-solving count, accuracy rate trends, and continuous study days in real-time. Records that accumulate little by little each day help build consistency.

**Light & Dark Themes**
You can follow system settings or choose your own, ensuring comfortable viewing even when studying late at night.

**Tablet Support**
You can study comfortably on tablets as well as mobile phones with a layout optimized for large screens.

**Offline Study**
You can solve problems even without an internet connection. Study without interruption, even on the subway or bus.

**Device Synchronization**
Once you log in, your study records and review schedules are securely stored, allowing you to continue studying even if you switch devices.

[Content Guide]

Past exam questions are not included. This is because the National Examination for Certified Nursing Assistants does not disclose exam questions, and since the copyright for past exam questions belongs to the administering body, copying and pasting them verbatim is not permitted. Instead, we have analyzed the KNHIS's question standards and created study questions tailored to the actual exam format (multiple choice, 5 options) and difficulty level. The questions are composed of core question types with a high probability of appearing on the exam, and we do not restore or reproduce past exam questions.
