Prepare for school exams!

Among the school exam questions, the questions with a high rate of appearance were presented in three stages.

[Exam Questions: 1 Minute Cut]
[Level 1 Challenge Problem: 3 Minutes]
[Absolute Grade Completion Problem: 7-Minute Cut]
You can develop a sense of reality by practicing solving problems within a limited time, and build solid skills by solving the three steps in sequence.

A problem of a different level!

It consists of problems that can develop mathematical thinking and problem-solving skills, such as problems that can be solved intuitively by interpreting the principles and problems that require integrated thinking across various fields.

Neat explanation!

We analyze the intent of the problem and provide clues to solving it, as if we were teaching one-on-one.
Additionally, it analyzes the problem from different perspectives and provides additional explanations.
