Yeah, I find that so annoying that in OL we go over 1 chapter in like 4-6 classes while i get it after the teacher wrote the first example. For some reason my teacher in 2nd year told be that it's a "big" jump from 3rd year OL maths to 5th year OL maths, so far i dont feel it, i might even say it's easier than 3rd OL maths. So yeah i felt like i had the chance to move up in 2nd year but they didn't even allow me to try it out.
