i did methods last year, without having done 1+2. in year 10, i did well in math BUT the stuff we learned in year 10, in all honesty, wasn't entirely useful for methods 1 +2. it was really more further math based with a little algebra. therefore, i kind of regret not doing 1+2 cause i didn't have the groundwork BUT i wouldn't have been able to fit it in my (already full) timetable. i quite literally died last year... kept getting c's and d's, somehow pulled my head out of my arse at the end of the year to get a low b plus. i hated the subject (except the calculus bits), didn't like the teacher.
on the other hand, this year, i did spesh, without doing GMA. still had the same teacher (ugh, gag, yuck, he tried to kick me out of his class at the start of the year but i managed to stay in). half of the class are failing, and they all did GMA last year. this year, i'm loving spesh. quite literally. i'm on top of all of the work, and mostly pulling a's and am at the top of the cohort. it's entirely possible to do spesh without GMA... and it's probably funner, i reckon.
