Hello, Lintao! I am sorry to hear that you failed the exam. Don't worry .Because it is not useful to be unhappy. The most important thing is finding out the main reason .And then try to make up for it .First i think you should form the habit of reviewing and pre-reading .Because only in that way can you grasp the lessons well. Second you should turn to your classmates and teachers for help when you have problems. I hope that you can make progress. Hello, Lintao! I am sorry to hear that you failed the exam.
