Videos cannot be underlined like books, but with the Vifovi method it is as if you would. We can say that this is a "Video Underline" method.There are students who can pass a subject studying only 3 weeks: the week of exams for the first term, the week of the final exam, and the week of the supplementary exam or improvement. Could it be that mathematically it is possible to learn 56 hours of class in just 3 weeks, having countless separate obligations?
