About this app
For the Information Processing Engineer (ICP) written exam, passing depends more on how you review than on how many questions you solve.
ICP is not an app that merely increases the number of practice questions. It is designed to help you identify your current weaknesses by solving over 6,800 questions, and to allow you to review questions right before you forget them. The cognitive science-based FSRS algorithm analyzes the forgetting curve for each question to automatically determine the optimal time for review.

You can master key concepts and question types evenly through questions created in-house that reflect the NCS examination standards.

[Content Guide]
The IT Professional Certification Exam does not include past exam questions. This is because the written exam for the Information Processing Engineer certification is conducted as a computer-based test (CBT), meaning actual exam questions are not publicly disclosed. Furthermore, 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 National Competency Standards (NCS) criteria 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 exam questions.
This app is an independent private learning tool designed to assist with preparation for the Information Processing Engineer written 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.
[Recommended for]
Those preparing for the Information Processing Engineer written exam for the first time
Office workers aiming to pass through self-study
Those who gave up because managing incorrect answers was cumbersome
Those who want to study briefly using their commute time
