Tests are extremely psychological. Whilst teachers try their best to bore you with an absurd amount of information, they'll secretly hide all their test answers in there. To get the good stuff, you'll need to endure through all the irrelevant aspects.
It's a true test of mental endurance. Once you've gained all the correct answers, it's extremely easy to cheat on any exam. Make sure to hide the answers in your memories since the technology to search them isn't public yet.
