Q14 c is also just a reworded copy of Q11 exercise 3c page 110 in Cambridge

2025 might just be the worst year, even worse than 2020

 

[tywebb]

u reckon this question is wrong?



why might it be wrong?

consider this solution







or perhaps reimagining this as a primary school question





What they might have meant was something like



so bets are on that they will change the question when they put it on their website

 

[tywebb]

there is a precedent for this.

in 2001 there was a wrong question - and they changed the question when they put it on their website!

 

[tywebb]

so in 2001 the question that got changed after the event was 7b.

when it went up on their website it looked like this

 

[coolcat6778]

they also haven't published the extension 2 exam despite advanced going up already

 

[tywebb]

there are 3 possibilities

1. they put up the original paper and get criticised for the mistake

2. they put it up but change the question and get criticised for changing it after the exam finished

3. they never put the paper up and get criticised for not putting it up.

would it affect marking? would they cut marks ?

they messed up with who they outsourced the exam creation to. I think they should all be fucking sued. this is worse than the vce leak, as the questions are suppose to be differentiating and unseen

 

[tywebb]

questions are suppose to be differentiating

more important than differentiating is valid and reliable.

considering the solution i put up before question 13a in the 2025 paper is neither valid nor reliable as an assessment item for extension 2 content

if they are aware of this issue it is even possible the question doesn't get marked at all - is disregarded and 3 marks deducted from total

 

[t234]

would they inform students of this? and if so when would that be??
of the mark deduction

more important than differentiating is valid and reliable.

please cancel the entire paper

 

[tywebb]

i guess there is a 4th possibility - put the paper up and delete Q13a - and then get criticised for deleting it

 

[tywebb]

so in keeping with the purpose of this thread i make the following prediction:

Q13a will be redacted.

 

[tywebb]

i'm going to rename Q13a as the 67 question

Show 6 is a constant multiplied by 7

Q13(a) was the only original question in the paper and they couldn’t get it right. LOL. They should get Chat GPT to set the paper.

 

[Allan Mekisic]

Just looking at the projectile question in 16(b). Shouldn’t sin0 be -3/5?
