advice about save the problem

Dear Tony,It is wrong to let Michael copy your answers. You should tell him that copy your answers doesn't improve his mark of chemistry and It's not honest.If you don't want Michael to to get into trouble, you can help him with his chemistry. You can tell him how to do well in chemistry and give him some useful suggestions. I think he can do well in his chemistry by his work hard at last.I hope that my advice can be be useful to you. Yours Li Ming.
