Sorry for the delay everybody. I won't be able to release these until probably around 11pm or so because I'm teaching swimming until around 9:45pm tonight, but then I'll be hungry and want to eat dinner so make that closer to midnight.

I'm almost done, but spent most of my time explaining a few assumptions that students had to make to get out the question. In particular, I spent some time clarifying Q12 (c) (ii) and Q16 (c) (ii). I also have a few nice alternative methods that you may/may not have seen before, so I hope you'll find them useful when they come out.

Please forgive me.

EDIT: Here you go.

Okay I've uploaded them everybody. Please take a look and let me know if you find any errors. I've made an effort to include as many alternative solutions as I could, within reason. In particular, I think you guys may like the alternative solution to the perms/combs Q14, the parametrics first part, and the 4-marker in Q14.

Hi Carrotstick, q3’s explanation you made an error; it should be Lim x->0

Additionally, could you upload the paper for this year’s 3u test ^^
