I'm in grade 10, for all you people in grade 9 XD, grade 10 is so much better coursewise on what you want to take and even more off school activites. Also you're not "The new kids on the block" anymore and have nothing to fear XD.
Its grade 11 that I fear, because just yesterday I had to fill out a course selection sheet for grade 11 so I had the option of choosing SIX subjects that I wanted to take insted of the normal two that aren't mandatory, its in a way sort of intimidating having to choose courses that reflect heavily on what I want to do when I get older.
