A-levels in mathematics. So I convinced the teacher

Why did this have to happen to me of all people? In order to imitate my Abitur in evening classes, I went to university in the evening for 2 years. Yes, I've got my final exams now!. But I really had to cheat at maths. My other subjects were sports, biology, and English. Math is the only subject I really had trouble with. I blacked out completely in the exam! Please don't think that I can't do the math, but the fear of exams made me lose my mind. The math teacher was a real Ar...l.ch! Surely a student would notice if the teacher would like to give "private lessons". Of course, I noticed when I left the university lecture hall in the evening, how the teacher pointed at my ar... looking at my ar... I had no chance in the exam, I was at his mercy. I am ashamed that I only passed that kind of math.
