About this app

For the Certified Real Estate Agent exam, the timing of repetition determines your success.

Gongin is a learning app based on cognitive science that focuses not simply on solving a large number of problems, but on reviewing right before you forget. The FSRS algorithm analyzes the forgetting curve of each question and automatically schedules a review just before you forget. Even with the same amount of time invested, the retention rate is different.

[Key Features]

Includes official Q-net past exam questions

1,400 questions across all subjects from 7 exam sessions (1st and 2nd rounds)

FSRS Smart Review

Spreads the gap between correct answers and quickly repeats incorrect ones. You do not need to manage your own error notes; the app automatically creates the optimal review schedule for you.

Incorrect Answer Explanations by Choice

Provides explanations for all five answer choices so you can understand why a particular option is incorrect within 5 seconds. This is different from learning apps that only show the correct answer.

Weakness Heatmap

Check the correct answer rates by subject and unit at a glance. Visually identify your weak areas and focus on them. Reflecting 2026 Revised Laws

Current laws have been reflected in the answers and explanations. You won't waste your time studying with outdated regulations.

Offline Learning

Review without interruption, even in subway tunnels or rural environments. Make the most of your commute and travel time.

No Ads (After Subscription)

Your concentration will not be interrupted. Ads are displayed only during the free trial.

[Recommended for]

Those who find the 1 million won lifetime online lecture pass burdensome but feel that YouTube and textbooks alone lack structure.

Students in their 30s to 50s who can consistently secure 15 minutes of spare time during commutes, housework, or before bed.

Those who want to complete both the first and second rounds of the exam in one app.

Those who gave up because managing incorrect answers was cumbersome.

You can start for free, and with a Premium subscription, you can access all questions and all features.

Premium Features: Unlimited questions, FSRS Smart Review, Weakness Heatmap, Incorrect Answer Explanations by Choice, Ad Removal.

** [Content Source]

1,400 official past exam questions from Q-net (Human Resources Development Service of Korea) have been included exactly as they appear in the original text.
