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.

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)

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!
