About this app

Passing the ADsP depends more on how you review than on how many problems you solve.

AD is not an app that merely increases the number of problems. It focuses on pinpointing your current weaknesses and retrieving problems you have solved just before you forget them. Because the cognitive science-based FSRS algorithm analyzes the forgetting curve for each problem to automatically determine the optimal time for review, you can reliably surpass the passing score by reducing wasted time in the 60% weighting of data analysis, even with the same amount of time invested.

[Key Features]

134 Concept Lectures, Total 14 Hours

You do not have to start by solving problems. The 3 subjects are divided into 8 sections, with 134 lessons summarizing concepts in approximately 6 minutes per session. Each lesson includes key definitions, everyday analogies, real-life examples, common pitfalls, and recent exam trends. It concludes with verification questions that allow you to recall what you just learned on your own. Unlike summary books that are meant only for reading, concepts and problems are linked, allowing you to move directly to the relevant questions as soon as you finish a lecture.

Over 4,800 Questions, Full Range of 3 Subjects

From Data Understanding and Data Analysis Planning to Data Analysis. Produced in-house to reflect KDATA's examination standards.

Detailed Explanations (Free Preview Available)

Each question includes in-depth, detailed explanations. We don't just check the answer and move on; we cover key concepts, common pitfalls, comparisons of confusing concepts, and memorization tips for each question. You can view the detailed explanations directly via preview, even without the Premium plan.

Various Solution Modes

You can choose to solve problems by subject or chapter, and progress and proficiency levels are displayed for each chapter. You can start with unsolved questions or gather and focus on your weak chapters. Anyone can also use the free Shuffle Mode, which mixes all subjects randomly.

FSRS Smart Review

The review interval for questions you answer correctly is extended, while frequently missed questions are shown again quickly. 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 time just when you are about to forget. Daily study reminders and FSRS review time notifications 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 the concepts you have organized.

Practical Mock Tests
We have prepared 10 sets in the same format as the actual exam, consisting of 50 questions in 90 minutes. It automatically grades scores by subject, whether you fail (40 points per subject), and whether you pass (average 60 points), and manages your highest scores and test history.

Learning Statistics and Continuous Study
Check daily problem-solving counts, correct answer rate trends, and continuous study days in real-time. Records that accumulate little by little every day help build consistency.

Exam Schedule D-Day
Check upcoming ADsP exam schedules directly from the home screen. Light, Dark Theme

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

Offline Learning

You can solve problems even without an internet connection. It remains seamless even on subways or airplanes.

[Content Guide]

AD does not include past exam questions. This is because the ADsP written exam questions are not publicly disclosed, and the copyright for past questions belongs to the administering body, so copying and pasting them as is is not permitted. Instead, we have analyzed KDATA's exam standards and created study questions tailored to the format and difficulty level of the actual exam. 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 questions.

This app is an independent private learning tool designed to assist with studying for the ADsP (Associate Data Analyst) written exam. It is not affiliated with or represents any government or public institution, such as the Korea Data Industry Promotion Agency (KDATA).

Non-majors in their 20s and 30s preparing to enter the data field
