Well I think there are many problems with the education system. It's quite hard for me to say this because I am only good at a few subjects. We really don't give a very well rounded education. A levels should go on for another two years imo and you must do at least two STEM subjects, one language and a humanities. For me, I would really struggle with a language and humanities, but I know that it would actually be good for me to learn. Also I feel that we really need to subsidise apprenticeships as well as University.
Now there is also a problem with rote learners, if you ask anyone with top grades how they revised then most people will say past papers. Only the very top Universities try and differentiate between rote learners and people who are talented. The way they do this is with aptitude tests, but really they are only common with Oxbridge. Most Russell group Universities won't do any testing. Just to prove how rote the A level exams are, here is a simple question.
"Prove that multiplying two minus numbers gives a positive answer" I can bet that 99 % of people including me, can't think of an Algebraic way of answering this question. It's actually very simple, but it requires some thought. The whole exam system is based off being able to answer questions that you expect, so it's no wonder that there are a lot of A* students.
My final problem with the education system is that there are a lot of students who just trickle through it with low grades onto a bad University to get a degree in a subject completely unrelated to their career. People actually need to understand that University is not just about getting smashed each weekend, and you are supposed to make use of that money we lended you. Even if you enjoy making films or love taking photos of flowers. It does not mean that you should do a course in it. University is somewhat about enjoying yourself but also giving you good job prospects.
