52/70

this year’s would probably be 50 then

the projectile motion question is a physics question asked in the WACE lol

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?

Nooo that question cooked me and usually I do well at projectile motion
I derived displacement formulas at least?

proof hsc physics wasn't challenging enough. i did this question before with physics formulas. what i did differently today was derive the physics formulas as we had to

Nah like 51 imo

any solutions out for mx1?

 

[coolcat6778]

This ATAR question was so difficult, the average WA student scored just 35 per cent

Mathematics expert and lecturer at Murdoch University Dr Brendan Florio said it was a “discriminator question” that set the top students apart.

I only did this question before cause I wanted to see if I could do it (i could) as it made news in WA as the hardest question in their physics exam

smo pls

im actually emo i calculated a 47/70 just now

was student number printed on each writing booklet like q11,12,13,14??

on each quetsion booklet but not spares though

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

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?
