This app is a tool that allows you to efficiently study more than 900 geography questions for junior high school entrance exams using a unique question algorithm based on the forgetting curve.

Main features:
・High-speed learning using self-grading method
・Question algorithm based on forgetting curve theory
- Consolidation of memory and development of instantaneous ability using question algorithms across all regions
・Basic and applied learning using blank maps and field-specific problems
・Review function with “problems you got wrong today” and “problems registered as weak”


◆About self-grading method
Although there is a handwriting space in the answer column of this application, there is no scoring function based on automatic character recognition.
We use a self-grading method (tap "Correct" or "Incorrect" by yourself) while looking at the correct answers.
This results in
・Improve learning speed
・Quick processing of familiar problems
・Avoiding character recognition errors
We are realizing this.
To ensure mastery, we recommend that you grade yourself harshly.
(If you are not confident, tap "Incorrect" etc.)
