Yeah... my teacher made hard tests so she said 80% but by the last test she knew our class of 10 MX1 students well enough to know who would do MX2 and her last test was hard so the kids that got 74%+ got in.
I got 78%.
but I had been saying since year 7 that i would do MX2
Ask your teacher, they will tell you.
My teacher said 80%+ in her tests from the start and i got: 64%, 56%, 81% and 78%
And our MX2 class is a big class at our school with 4 students, the class above us had 3 and they said that was a lot.
But our MX1 class is small with 8, they usually have 15ish.
Btw, my school ranked 120something this year.
