I think make up a missed lesson after class is completely unnecessary, but would be counter-productive. Tuition classes outside of class is a specification now. It is has become a popular fashion and imperative students to take out enrichment classes outside of the school curriculum. Most of these students need guidance in their school work, while others join in order to stay ahead. It has become such a lucrative business that so many enrichment classes stem out suddenly, making the industry highly profitable and attractive. While everyone to attend these classes, the quality and standards of teachers are sometimes serious suspicion. Also, how many students can learn from these classes is another issue. Many classes are held beyond classroom time, means students have to attend additional classes and the extension of the time they spend in learning. They will only add to their burden of study, and does not get personal ascension, natural to study also won't to improve. There is no need to so make up a missed lesson after class.
