Citizen quiz app.
Let's solve it as a measure for the National Center Test for University Admissions (common test for university admissions). There are some difficult problems from the basic formula questions, so please try to solve them even for junior high school students who are refraining from high school life.

* This app alone cannot cover the entire range. I hope this app will increase your motivation for studying. Also, if you have any mistakes, we would appreciate it if you could point them out. I look forward to working with you.
