Sorry to bring back an old comment, but I find it interesting to see this bc it’s such a different way of learning to what I’ve experienced. I did two-variable equations in the equivalent of 6th grade and I didn’t get around to learning about the imaginary unit i
until the equivalent of 12th grade. I guess you guys must learn stuff in bigger ‘chunks’ rather than loads of different topics — for my first major set of exams, I was tested on about 20 different chapters of content learned over 2 and a bit years.
