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 many 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 differs.
