Learning is a consistent process and you will encounter  many difficulties. Should you give up? No,keep going. You will find a right way in the process of learning. With practices, I believe that your English will reach a high level. 

Today is a gift. Just leave all your sadness in yesterday. By the way, scores or grades in school are just a small part of your entire life; everything will be okay! 

Come on, cheer up, everything will be fine. Don't worry too much and just keep going. You're the best.

Take everything you faced today as your fortune in the future.

It just a score, life is colorful, study is only a small part.

Love it and just do it. Treat every single test as a chance to learn the English news and interesting survey. Take it easy to accumulate your knowledge of English. I'm sure that you will enjoy what you learn.😄

In my opinion, the most important thing is to keep the passion for English, and it's also a good habit to help you for your different part of life. Trust me, I'm also a high school student who loves English now (maybe there are so many mistakes I made in grammar, but I am not afraid to try)

l think you are an excellent student, trust my judgment and also believe in yourself!

Don't be so sad. Just trust yourself!

Just do your best. Ask your teachers and classmates for help and find out the reason. Do not care too much about score. The progress is very important.
