My last exam

On Monday, I took an exam about Elasticity and Materials Resistance at University.I had been studying for 2 weeks and I thought I was prepared to pass it well. I understood all the units and the main objectives. I wasn't fairly nervous and I was trying to convince myself that the exam wouldn't be difficult.

This morning, after my class, I met with 2 classmates to study together until the dinner time. Afterwards, we went to eat a sandwich until the exam began. When we finished, we came to the University again to our class. At 2.45 the exam began. It was strange...The first question wasn't easy... but the second neither....
When I gave the exam to the teacher, I knew that I had failed the exam, I was absolutely furious but I thought I could have a bit test points.

This was until tomorrow, when we corrected the exam in class. Then I saw that all my questions were wrong. I felt very disappointed and now I don't want to know my mark.
The teacher said that the marks will be publicated on Monday, but I prefer not to know them. The engineering is difficult, but sometimes it seems that study is not that you need to pass the exams. All you need is to be inspirited at this moment or just pray to someone who can help you.
