Dear Wang Wei
I‘m very happy to hear from you.But I feel a little sorry to hear you failed the first examination.Don't be so sad.Take it easy.I think you can do better next time.Don't be so nervous,just be relaxing.Have a good rest,and then put your heart into study.And listen to your teacher carefully.Do your homework carefully.You'd better preview your lessons before class.I'm sure you can win the next examination.I hope your secusses.
Yours,
