I'm late

Today I wake up a little late. When I opened my eyes. I didn't believe the time. Time is indicated 8:10 AM. I'm usually wake up at 7:00 AM. But today is not. I was very afraid. I don't want late to the class. I made a mad dash out of the my house. When I arrived subway station that time is 8:30 AM . It's seem like mission impossible. But I arrived class room that time is 9:40AM. Prof. godfrey class. I just solved one question. I'll never being late.
