Put various drills in your smartphone and study anytime, anywhere! Known has a wide variety of drills, from learning drills for elementary school students to workbooks for qualification exams!

The digital drill app "Known" is a new style of learning app that dramatically enhances the effect of repeated learning by allowing you to directly write down the process of answering and notes on the solution on the problem, so you can confirm the past learning history and consolidate your memory. In addition, it is equipped with functions unique to digital technology, such as automatic grading, automatic re-asking of questions based on past learning history, and accumulation and analysis of learning results, providing the optimal learning method for each individual user.

■ You can do the following with "Known".
