Grew up watching how many of my colleagues in class were cheating their exams.
I myself have cheated once in my life, during an exam of mathematics in 4th ESO (10th grade), it was the last exam of the year and I had to pass it no matter what so I ended up having tiny notes on the back of my calculator, where the batteries go, with the formulas written on them as I was unable to memorize all the formulas.
However many of my colleagues cheated regularly and for any type of exam.
