pretty sure mx1 won't count, and half of society will count/half won't count.
even though i would much rather study maths than society, i have like 10 free days to study society whereas mx1 is on my week which i have maths/modern/mx1/ancient so study time speaking, i just dont have the time to learn the course, plus i need to go really well in the maths hsc since my marks this year have been kinda crappy...therefore, im giving up on mx1.
i kept mx1 because id been in the same maths class for 3 years, i didnt realise until about half way through the year how shit i was starting to go in mx1, and really couldn't be bothered dropping out of my class since i just liked the class so much, and my teacher was good for maths (it was just me who didn't put in the effort).
in hindsight i should have dropped society at the end of year 11 when i picked up history ext, then i could have had more time to study mx1, but i wasnt sure if id be any good at hx soo...i kept society.
