Combining sentences.
When going to school I knew that I should have studied for that test that I was going to take. I walked in 10 minutes late and my teacher said "Try your hardest to be here on time, ok?" I sat down and said "I will next time" and started my test. I noticed that there was lettuce all over the table, but I didn't want to question it, so I went on with my test. After school I walked out and my friend said that she was going to the mall. I asked her if I could come with her, and she said "Sure". When we started walking I asked her if she wanted to go to Subway and she said " I don't have any money on me." I said "It's ok don't worry about it cause I'm going to pay for you." She nodded her head and said "Thank you".Then she started tellling me this crazy story about a tornado that unexpectedly hitting Chili.
