The effectiveness of the courses depends on 80% of the student. The teacher can teach him, give interesting tasks, use interactive teaching methods. However, if a student does not want to study, the courses will not be practical. Of course, not all people are like that. Some people need to spend several hours reading books and assimilating the material. When I was in college, I couldn't pass physics, no matter how hard I tried. Therefore, I went to a tutor for several months, whom I found on a website I'm not allowed to advertise here. First of all, see if the formed courses are suitable for you.
