Today's test

Today I had a test which is introduction of English linguistic. I studied it all night. I don't study late at night because I will sleep when I take a test. But I am afraid that in case of lost the credit. So I studied late at night. I went to the bed at three am and woke up five am. I slept for two hours. I studied for a hour, but I felt bad headache. So I went to bed and slept for one hour. When I woke up again, the headache was better than before, but I had a poor appetite. Anyway, I did my best for the test. Finally, the test came. I expected the test's difficulty. It was very difficult. Now I am afraid that there is a possibility of losting credit. I hope I pass the credit.
