It’s currently university exam season in my country. My roommate has quite literally not come to university at all the entire semester except for mandatory stuff; hasn’t studied at all, doesn’t even have the coursework, 0 notebooks or folders, etc. We’re more than half done with the exam session and he got 10/10 (max grade) at each exam. He just read through my coursework the day before the exam for a bit & that was it. When I ask him he says he uses intuition, logic and reading between the lines to understand the “patterns”. I just don’t understand how you can use “intuition” for microeconomics & math applied in economics for example. I know for a fact he doesn’t cheat cause in his mind cheating is too much effort.
I did this through high school by listening in class, the teachers explained the material then assigned homework, which I did not do, then tests, which I crushed with near 100% accuracy, then got a C grade in most classes because I don’t do the work, only the tests. Also tested out of the first year of college. Was just good at taking tests I guess.
In university though - I did have to study and do the homework to ace the exams. That was more specialized (accounting).
ETA: your friend sounds like an absolute testing savant. I don’t know how that will translate to a job though.
