More people think the student go extra class is waste money of their parents, it is not very true because if the student go to extra class they'll know much knowledge, but if they stay at home and just go to school in monday to friday, they just know basic knowledge and don't know advanced knowledge. Others people think the parents should for their children go to extra class, that is right. Because the student need study, they did know the basic knowledge in the school, if want succeed and get a good job they need study advanced in extra class.

the end, my opinion is the student need go to extra class to broad understanding of the world and a lot of things. The parents'll don't need toil, their children will take care of them for the rest of their lives.

According to some people,extra classes is unnecessary.But to the others,this is good for students as they can practice more and become a good students with good grades.But in some special cases when bad students become worse because in some extra classes there are a lot of students with poor morality .So that the bad students became worse as they copy the bad morality and behaviours from worst students.In my opinion,going to extra classes students will be able to understand the basics, study effectively for exams,review and master basic knowledge without losing or gaping knowledge.So extra classes in my opinion is very good for students if they know how to learn effectively as to notwaste effort, time and money.
