Outside school activities...

I am involved in tuition classes on Wednesday and Saturday.I spent two days on these activities.Each of my tuition period is 1 and a half hour.I am involved in these activities to gain more knowledge, learn more on the subject and more.I think it is neccesary for me to participate in these activities as it is useful to me and the teacher's time is flexible for me to accomodate my cirricular activities.These activities does not affect my studies and in fact helps me to improve my grades.I get stressed sometimes with too much activities going on and piles of test papers for me to work on.If it is useful, I think it is ok students to get involved in outside school activities, but they should not get too occupied with their activities and neglect their studies.
