exams I don't know why some people exists in our educational system? I am talking about a professor in my university that he is awful in teaching and he is so much lazy to even give us neat methods in solving. Next Sunday I have my final exam in university and today I was studying for that and I realized that i have to guess the answers basically. Honestly I didn't go to his classes in university Cuz they were set in the morning and I preferred sleeping :) Although the way that he is teaching is awful. Imagine a tired man who is standing in front of the whiteboard on a boring Monday morning and he is talking in a way that you will be sleep for a minute later. So I had this right to choose sleeping in my bed from sleeping in the classroom. Now imagine me opening my books today and see some new lessons that I hadn't heard, then see the notes of my classmates who were present in the class and finally I saw the sample questions which the professor gave us. The resource book and the notes were totally different and the questions was so hard. Now I am extremely sad and my mind is full of stress for the next Sunday.
