okay cool, didn’t have spares
thank you i was panicking

nesa knows that students are having a stressful time, even if you messed your number up or missed it they wouldn't let something like that get through most likely

What raw mark do you reckon would give 80 or 90 aligned this year

 

[coolcat6778]

on each quetsion booklet but not spares though

and they are completely different design as well. Why can't they standardize the design?

idk i didnt notice that

could be like 38 to 52

hypothetically if someone didn’t write their number in the spare would invigilators check? and fill it in?

this entire thing could all be avoided if we did our working in just one booklet rather than like 6 separate sheets of a3

they should check all exams before they go in the mail. my class for extension 2 is me, and for extension 1 is me and another, and the invigilator was my teacher from primary school so she just checked them then and there. But, they should all be checked

idk why they have to be lined its so bad d

lined is good, they should just make the line fainter. also 1 cm spacing is the best, i don't have to write like i have a micro penis

i would agree, however i carry a bunch of blank paper instead of a book

Wait guys for the q where it was like dy/dx = 5/y i left my andwer as y=plus (the eqn), i wrotr the minus case first and gave the justification cos when x=0, y<0 but i crossrd it out and put just the positive versioj cos i was thinkijg that like since 16 = 4^2 then sqrt of 4^2 will be absolute of 4 so it can be -4, will i lose a mark?

well the answer is -root( ) and bc u put the positive version instead, I'd assume that you'd lose a mark for that

Yeah sorry to say, but you'd definetly lose a mark for that since the answer is the negative square root.

Just realised I completely screwed up on that q...

Isn't the binomial question answer 26, not 44?

Yep, losing a mark on that question

yea answer is 26

a fair few mistakes in these solutions btw
