About this app

The Information Processing Engineer (ICP) Practical Exam is Not a Multiple Choice Test.

The reason you might pass the written exam but get stuck on the practical one is clear. This is because the practical exam requires you to write out answers yourself, covering short-answer questions, descriptive answers, SQL, and code. This learning app focuses on practicing the exact format of the actual exam and reviewing scientifically. Because the cognitive science-based FSRS algorithm analyzes the forgetting curve for each question to automatically determine the optimal review time, the amount of information retained differs even with the same amount of time spent.

[Key Features]

4 Modes of Actual Exam Formats

Practice by writing out answers yourself, matching the format of the actual exam, ranging from written questions like short answers and descriptive answers to practical tasks like writing SQL and code. Break away from the habit of only solving multiple-choice questions and train yourself to write by hand.

Over 1,500 Questions, Detailed Explanations

We have included over 1,500 questions created in-house based on an analysis of Q-Net exam standards. With explanations that pinpoint the reasoning behind the correct answer and identify potential pitfalls for each question, you can move on without simply checking the answer, understanding the underlying concepts behind it.

**Various Solution Modes**
You can select and solve problems by subject or unit, and your progress and proficiency levels are displayed for each unit. You can start with unsolved problems, focus on weak units, or perform random reviews by shuffling units.

**FSRS Smart Review**
It extends the review interval for questions you answer correctly and quickly revisits frequently missed questions. You don't need to manage an error notebook manually; the app takes care of the questions you need to review today, and you can even set the amount of material to review each day.

**Review Notifications**
It reminds you of review time just when you are about to forget. Receive study reminders at your desired time every day to help maintain your study flow.

[Content Guide]

We do not include past exam questions for the Information Processing Engineer (ICP) Practical Exam. This is because actual exam questions for the ICP 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 the Q-Net examination 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 ICP practical exam. It is not affiliated with or represents any government or public institution, such as the Human Resource Development Service of Korea (HRDK) or Q-Net.
