You seem blissfully unaware that school is a construct designed to suit most people most of the time. Exams are a very flawed basis to measure ability that in no way reflects the real world. It is simply a single method of measuring ability and it is very unrealistic in terms of how it measures.
in real life no one has to memorise 220 formula or 8 quotes from a text.
This method suits some people but not necessarily the best people. Just people whose brains and physical abilities suit the exam structure. Best selling authors have been dyslexic and failed school exams as have world class scientists. Should people like this fail to progress to the next level of education because the exam process is not designed for them even though they are far more brilliant?
You can do poorly in a maths exam not because you can’t do the most complex mathematics but because you are slower to read the question. It is not an English comprehension exam but your dyslexia will mean you are slower to read even though you might be the most brilliant mathematician in the school.
In the real world that brilliant mathematician will not be fucking up because they can’t spell. They will be creating complex algorithms NASA. Or they won’t because random people with zero understanding of how things work think the mathematician should have been curtailed at GCSE because they couldn’t read fast enough. Or couldn’t write fast enough because they had dyspraxia
