thanks i found it

I think the extension 1 exam was harder than 2021 and probably on par with last year. The MCQs were really hard and wasted time. Questions 11 and 12 were mostly straightforward except the binomial. Question 13 took a lot of time. Q 14 b was interesting and I think you had to substitute the y intercept from the graph into the equation. You then had to solve for x. I didn’t get anywhere with 14 c.

Wait guys for the second last part can you prove and use this to get it

Idk smth like that I got lucky cuz I saw smth like second last question in a paper
I used a right angled triangle to find sin and then everything cancelled nicely

25 past papers and lowest raw on the hsc love to see it

I got 10 as B, because I realised that since no more than 2 students can sit together, the general pattern must be the following, and then i worked from there (can someone verify dis)

 

[Luukas.2]

Yes, 10 is B.

The students must be arranged as two pairs plus a single student.

Seat the first teacher in 1 way.

There are three ways to seat the other two teachers, and 2 ways that they can be arranged.

The five students can then be seated in 5! ways

Thus, arrangements = 1 x 3 x 2 x 5! = 3! x 5!

what do yall think a 64 out of 70 will scale/align to for this exam?

 

[dsakvyilsa]

what do yall think a 64 out of 70 will scale/align to for this exam?

assuming it aligns similarly to last year, high 90's surely

bro i did almost 60 since mid year and i still couldn't get a mark on q 14 (i'm doing accelerated so i had a lot of time to grind)
