When I was a college student, I enjoyed doing lots of things with my frineds.  But I was interested in other things than my class at school so that I used to escape from some lecture and talk with other students.  Although I enjoyed talking at that time, now I regret the ridiculous school life very much.  I could not improve my ability efficiently when I was a student.  Therefore, I strongly agree with the statement that students should attend their classes.  In my experiences, classes at school have two beneficial point for students. 

 

  Lecture of experties is very useful for students to know the point of study efficiently. At school, experienced professors give us lecture based on their result of their long time research.  Students, therefore, know what is the important point of the subjects and secret key to acquire some skills without taking much time.   If they try develop their knowledge and technique only for themselves, they would take much more time to know these useful tricks.  Thus professors' explanations about subjects at classes are very important.

 

  Classes enables us to learn with other classmates, which teach students some important things which cannot be learned at studens alone.   Discussion with others build up students' communication skills and broaden their own idea and points of view.  They also learn the importance of cooperative attitude for achieve their common goal as well as the way of expressing their own opinion clearly.   Such things are necessary to know because in the future, students will have to colaborate with colleagues or to negotiate with other workers in the society.  Students in college, therefore, should learn such things from the lecture of university. 

 

  As I mentioned earlier, classes are essential opportunities for students to increase their knowledge efficiently and brush up their own communication skills.  Of course some intelligent students can acquire these things alone at home by using some devices like internet,  However most students need first guide of professor in discovering the way of studying for themselves or acquiring the basic knowledge and communication skills.  Therefore being absent at classes seems to waste their precious opportunities of education,  To improve their own academic and communication ability, students had better attend their classes as much as possible.
