Remembered Event Essay

I passed by many worried faces and many students walking with their books open. I assumed they were cramming before their exams. I thought to myself, "You guys should have studied last night. Cramming won't help." I did not worry about my World History test, I was ready for it and because I was ready I was kind of excited. As I was walking with a posture telling the world, "I am ready to ace my tests!" I bumped into my friend that had the same class as me.

"Hey [my name]! Are you ready for the World History exam? I heard it's the hardest exam out of all the midterms! I studied but I don't know if I studied enough! I need to get an A on this exam to get an A in the class! My mom said she'll let me get my license if I get straight A's this semester! I just need to get an A on this exam then..." She ranted with a worried voice. She always worried before a test, even for a quiz but today it began to annoy me so I decided to throw in a word of encouragement.

I cut her off saying, "Don't worry, you'll do fine! You did well on all the other World History exams!"

"Hopefully. Did you study? Are you ready?" She seemed a little calmer.

"I studied all night last night I think I got down." I was sure I was going to do well.

"Yeah, well you're smart. You never get lower than a B plus on a test." She sounded jealous. "You should still look over your study guide before. I overheard someone from last period saying they didn't know the answers to half the test," she advised.

I giggled, "I think I'll be fine. It's in my back pack and I'm too lazy to take it out right now."

"Are you sure? You want me to get it out for you?"

"No it's okay, I'll do it. But I don't think I will need it though."

We went to the classroom together and I anxiously waited for the exam to start. The teacher came to the classroom and handed us 6 pages of the exam sheets. The exam duration was an hour and half.

The first few questions were easy but it became more difficult in the next questions. I could not understand what the questions were asking and I could not even remember the things that I had read the night before the exam. My eyes went blank.

I turned in the exam and I felt ashamed and remorseful at the way I had behaved earlier.

(Feel free to add sentences and ideas! Thank you very much!)

Why do you have to feel ashamed of what you behaved earlier?

I don't think it's really critical.
If you have prepared well for the test, you should be proud. And what happens during the test is just the matter of luck.

I do not check my brain again before the test. I let it free and clear.
So what do you ashamed?

If you felt so, please made it as an paragraph. Your one sentence does not explain anything. Explain why you feel so. Tell us more what you did at that time. And tell us more if you improved this problems? What did you do to improve your mistake?
