The school system as we know it, is & has been shaping students to fit the system which they live in and throughout this process, the students are forced to learn(mostly memorize) subjects which they do not have any interest in whatsoever and because of this they can't score high in school. It is as if our brains are trying to avoid information, which is out of interest, as much as possible. But when there's something in interest it is damn easy to collect and comprehend that information.
Let's assume that you are a programmer and you are greatly amazed by that, you love solving problems and develop software, you read lots of documentations and contribute on other peoples projects without even having to worry about "remembering" what you're reading, everything is easily understood and there's no issue with that. But when you have to learn about politics and how the system works, it appears as cancer to your eyes because you have no interest in it, there's no will to collect that information and therefore you score low in that subject.
now my question is: Why can't we learn what we don't like? (what we're not interested in?)
