Skyeng is an ecosystem of services for learning English with a personal teacher. Skyeng combines teaching competencies and IT technologies on one platform to achieve the maximum effect for each student. All textbooks are digitized and presented on the platform in the form of exercises targeting basic linguistic skills, such as reading, speaking, listening and writing. The tasks are checked automatically and materials are updated by content developers in real time. This reduces the cost of textbooks and minimizes the time for checking homework and exercises in the classroom not only for students, but for teachers too.
