I found the education system as a whole pointless. As long as you can read and write, Your then free to learn about any subject you feel passionate about. All the rest is useless unless your interested in a specific subject like maths or science for example.
I think we should be taught to read, write and some basic maths and then encouraged at a younger age to think seriously about what we want to achieve. Then under go an education in that direction.
People will willingly learn and remember stuff there interseted in. I dont believe you can put a grade on intelligence. People are good at different things. So to put everyone under the same umbrella. Then say your less intelligent because the person standing next to you can remember certain things, you cant is rediculouse. And once someone is labled as less intelligent.
They blindly believe it and so lose the desire to achieve. The whole things a shambles but what you gonna do?
