We have published the Math Exams application for iOS, macOS, and Android. The application is to prepare high school students for the final math exam. Thanks to Ivan for this fantastic collaboration! I look forward to continuing to develop and improve this application. So that it will include more complex tasks, precisely check the answers, and suggest the fastest learning paths to the students individually.
