I remember having a cheating rig at high school. We were 4-5 classmates, who would always sit close and hangout. Each of us would study the classes we best at. For example I really sucked at English and math, but was really good at physics and biology, one guy was good at English and another one at Turkish literature, another at history, another at Math. Overall high school was really easy for us. It's not like we didn't cheat at exams, we also helped each other before the exams. Teachers tried to separate the group several times but we were smart and doing well, so they chose to ignore at some point. All members went to uni, studied STEM.

Now, I'm well aware that studying things you can already do is not the best way but this was what happened.
