A free program for Android, by Stepik.

This free app for Android devices is designed to help you pass the GMAT exam, which is a requirement for many universities. The course is based on a very comprehensive and useful GMAT exam problem-solving course, but it has been adapted for mobile devices.

The course has an adaptive problem-solving section, which means that you can not follow a linear pre-set structure of the course, the adaptive engine generates a unique path for each student. This is the case for all courses, not only for the GMAT exam.

This is because the students have different knowledge levels, and the adaptive engine takes into account the knowledge level to provide the best content for each student.

The app has a simple interface and a user-friendly layout.
