The introduction of digitalization and new technologies into the learning process has changed teaching approaches and has led to the wide use of online tests and quizzes as a form of both evaluating a student’s knowledge and providing tutoring across many subjects, including higher mathematics. The form and effectiveness of using online tests differ from subject to subject. Due to the specificity of higher mathematics topics, online tests and quizzes in higher mathematics should be used very carefully with applied restrictions and modifications. The experience of mathematics professors at Riga Technical University (RTU) shows that the use of online tests in higher mathematics should be well-balanced. The current research provides a detailed study on a very actual and disputable question about the effectiveness, specificity, advantages and disadvantages of using online tests and quizzes in teaching higher mathematics at universities for engineering specialities. This research is based on the RTU students’ and professors’ surveys, and is also complemented by reviews of recent publications in this area.
