Столбики vs School tests Usage & Stats

I created an application for my child in order to test and consolidate his knowledge of mathematics obtained in elementary school. Thanks to this application, my child has now graduated with honors from the math class. I think that this application can be useful for other parents as well. Therefore, I post this collection of tests in the public domain. If the application is in demand, I will add new questions to existing sections, and new sections of tests will also be added. The application currently includes thousands of questions on the following topics: 1. Addition; 2. Subtraction; 3. Multiplication table; 4. division table; 5. Work with time; 6. Tasks for percentages 7. Mathematical examples. This application is focused on creating your own tests based on existing sections of the question guide. This is used to test and reinforce the child's knowledge of specific topics. One of the important features of this application is the ability to view the errors made during the test. Now you can check your knowledge in the car and in the country, even without an Internet connection. I personally use the application in the following way. If the child passed the selected test and scored an acceptable score, then the child may be allocated time for games and videos on the device). ==== All the functionality of the application is available immediately and for free. However, if you like the application, I ask you to help in the development of the project by issuing a monthly subscription or provide one-time financial assistance, which will be aimed at improving the application and adding new interesting and useful features. If you purchase a monthly subscription, your iTunes account will be charged for the upcoming period unless you turn off auto-renewal or cancel the subscription in your account settings no later than 24 hours before the end of the current period.
