TestU Online is a free of charge, multilingual, online e-learning platform enabling easy and fast creation of various quizzes, tests, and exercises primarily intended for learning languages. The platform users will be mainly teachers, coaches/lecturers as well as their pupils, who are attending elementary schools, or other forms of education, whether formal or informal. The reasons for creating such a platform can be explained by the necessity for allowing a young generation to access free education despite their socio-economic, religious, or national background, geographical limitations, or even various kinds of disabilities.
