Dear Linda
I am fine reacently. How do you do? It is a difficult thing to learn English well in a short time. I cannot help you anymore on your stuy.But, in my opinion, your had better tell your parents your test. If they know your score from your teacher or others, you will have a bad end. Besides, they perhaps will teach you something to pass the exam.Of course, you can ask your teacher to treat your parents. It is a bad idea. At last, good luck.
yours
Mary
