Sister Jing Made Me Miss the College Entrance Examination

My sister is a busybody, and she refused to go out on the day of the college entrance examination. I was so anxious that I had to rush her. If she didn't leave, she would be late. However, she thinks that taking fifteen minutes less will not make any difference. Those with poor grades will still get bad grades if they take fifteen minutes longer. Those with good grades will still get good grades if they take fifteen minutes less. My mother also thought I was looking for trouble and slapped me hard. Later, both of us were late and were turned away from the examination room. When I opened my eyes again, I went back to the day I took the college entrance examination.
