Are we sure that question 13 core is option C Cause thats what I did and I don't want it to be wrong!

[Lucho23]

Thanks Dan1995 and Lucho23 for the clarification, turns out I just am retarded  Thanks again guys, sorry to be a pain

No problem  Make sure you ask, or else you'll keep making the same mistakes.

To anyone else who got E.. Check if you forgot to count the outliers at the end as points, the 3rd quartile should actually be 50, not 47

Definitely wearing glasses to my future exams -.-

"n=50"
My calculator has 46 numbers... I think I'll wear my glasses next time as well haha

[nugz]

I see it now, thanks.
I'm quite disappointed with 37/40, especially when I got full marks when I did the 2013 one
Do I still have a chance of like mid-40s if I get an A+ for Exam 2?

Thank you, I'll try redeem myself in Exam 2

The gradient is unchanged, so the answer is C.

Because you have to redraw them. All 4 can be rearranged and moved to become planar.

You have to redraw them to make it planar

Does anybody know how reliable the business maths solutions are? Because I know there's been a bit of debate over it, I'd prefer to know if there's any other questions (besides 9, though it is E) that are uncertain before I feel confident in my mark

[vcestudent123]

I almost forgot..
Thanks for the solutions guys It made me realise how much I need to start paying attention to the questions and not just assume things before finishing them.

Exam 2 will definitely be better than Exam 1 (hopefully)

Did anyone else find this year harder than recent years?

Did anyone else find this year harder than recent years?

I felt it was relatively on par with the previous years exams.

After going through all of the questions again, I felt that, as always, there were odd questions, but they were a bit more manageable this time around.

So you guys think that the cut off for A+ will be 37 again? Some years it has been 36
