Even though several years have passed, I still have a fresh memory about that test, which made me crazy.  Test, test, generally, before I have a test, I am very nervous; while I am taking a test, I am tense; after I have a test, I am crazy.  That time, just after the test, the questions and answers all appeared in my mind repeatedly.  I could not stop them.  I forgot to get off the train at my station.  I got off at the next station, and I needed to go back to my destination.  A man who worked on the metro, said, “Madam, it is the terminal”.  I did not hear it at the first time.  When he said it again, I heard.  Then I stood up and got out of the train.  Unfortunately, I had to take a train back because I was not where I needed to be.
