I did quite well with my O levels, but only when I realised the lessons weren't teaching me anything, and started taking the text books home and reading through them and taking my own notes in my own sweet way.
Somebody had this brilliant idea called student-centred learning where you'd choose what topics you wanted to study and design your own course, and the teachers would just be there in case you had any questions. Ever since I heard of it, I've not been able to understand why the whole education system isn't like that, but I suppose NTs actually get something out of conventional lectures, and I guess the employers feel more comfy with standard qualifications. Still, I've got AI chatbots these days and that works better than anything, as long as the chatbots doesn't make too many mistakes with its answers to questions. Employers' wishes don't matter to me any more
I learn what I'm interested in and ignore the rest.
