您好：Tuition classes outside of the curriculum is a norm nowadays. It has become fasionable and imperative for students to take out enrichment classes outside of their school curriculum. Most of these students need guidance in their school work while others join in order to keep ahead of the pack. It has become such a lucrative business that so many enrichment classes stem out suddenly, making the industry highly profitable and attractive. Although everyone attends these classes, the quality and standards of the teachers are sometimes serious points of doubts. Also, just how much can students learn from these classes is another issue. Many of these classes are held beyond classroom hours which means that the students have to attend additional classes and lengthen the time they spend on studying
