I'm a senior three student．I often do bad in my
exams，so I have been trying to catch up the others．
But I'm such concerned about my marks that sometimes
l cannot eat or sleep well at a night．I’m afraid that
I may get low 
marks in the tests again even if l work
hard than before． I have no courage to face low marks．
I cannot fix my mind to my study，whenever I think of
This. It is obvious that the worry had a bad effect on
my school works．I’m feeling very sad．Would you
please telling me how I should deal with my worry?
