◆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.)
