I feel like the author is really over doing these exams, like its a school for mercenaries basically. I don't see why you would make it seem like these tests are difficult, and if they really are why? they are the worst country for adventures and just the tests are so difficult to where the main character of the novel finds it hard to barely pass, pretty nonsensical. Not to mention the main character states that what they are studying is worthless and boring, what??? their jobs are to literally guard people gather things and kill people, what could they possibly put on these "difficult" exams
