This app is a tool that allows you to efficiently study more than 1,000 history questions for junior high school entrance exams using a unique questioning algorithm based on the forgetting curve.

Main features:
・High-speed learning using self-grading method
・Question algorithm based on forgetting curve theory
・Establishment of memory and fostering instantaneous ability through question algorithms throughout all eras
・Basic and applied learning based on problems by field and era
・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.)

◆About learning courses
This app has the following learning courses.
[All eras]
-This is a course that asks questions from all registered eras using a unique algorithm based on the forgetting curve.
-One set of 20 questions will be asked.
- Your proficiency level will change depending on whether you answer correctly or incorrectly.
(the aim)
Examination questions often include a mix of events and options from various eras, so even if you think you have studied and memorized chronologically, your memory may become confused within the short time limit. In this mode, questions from various eras are randomly asked, allowing you to memorize them deeply and improve your quick thinking skills.

[Year]
-This is a course that uses a unique algorithm based on the forgetting curve to ask questions that require answering year numbers.
-One set of 20 questions will be asked.
- Your proficiency level will change depending on whether you answer correctly or incorrectly.
(the aim)
Originally, history subjects should be studied while understanding the major trends and meanings of the times, but for junior high school entrance exam students who are required to answer questions in a variety of formats in a short amount of time, memorizing era names is a great weapon. It is a fact. Some of the era name questions are very difficult, but there are others that you can answer in an instant if you memorize them, so give them a try.

【culture】
-This is a course that uses a unique algorithm based on the forgetting curve to answer questions about the names of cultures.
-One set of 20 questions will be asked.
- Your proficiency level will change depending on whether you answer correctly or incorrectly.
(the aim)
As with all historical issues, simply learning about culture in chronological order is not sufficient for memorization. In junior high school entrance exams, which ask questions from all eras, the ability to instantly answer questions about culture based on events, buildings, works, etc. is a weapon.

【person】
-This is a course that uses a unique algorithm based on the forgetting curve to answer questions about people's names.
-One set of 20 questions will be asked.
- Your proficiency level will change depending on whether you answer correctly or incorrectly.
(the aim)
In junior high school entrance exams, there are many questions that use photographs and drawings. If a person can be identified from a photo alone, a lot of exam time can be saved. Also, by remembering related events while picturing a specific person in your mind, you can expect more efficient memory.

[By era]
-This is a course that asks questions from different eras using a unique algorithm based on the forgetting curve.
-One set of 20 questions will be asked.
- Your proficiency level will change depending on whether you answer correctly or incorrectly.
(the aim)
This is a course for learning by era. The proficiency level is independent from the all-era course, so you can first study by era and then test your skills in the all-era course. This course is recommended for 4th and 5th graders.

[Today's wrong question]
-This is a course where you review the questions you got wrong that day in each course.
- Your proficiency level does not change depending on whether you answer correctly or incorrectly.

[Problems registered as difficult]
-This is a course where you review problems registered as weak (manually registered) in each course.
- Your proficiency level does not change depending on whether you answer correctly or incorrectly.
