For me,I am only involved in tuituion which is on Wednesday,Thurday,Friday and Saturday.
I spent two hours on my tuitions on Wednesday,Thurday and Friday.
On Saturday,my tuition is three and the half hours.

I am involved in tuition to let me understand more about the subject and will understand
it easily.
Yes, I think it is necessary for us to have tuition because we can learn more about the subject.
No,it does not affect our study because by going tuition makes us know the subject better.
No.
No,it make no use of our time.
