Hello,
Thank you for uploading images of the walkthrough of the examination, im sure many people will find it helpful. However, may i refer you to your answer for question 9)c) of paper 1. With -40(x+5), would you not get -40x -200, to give you a final answer of -200/x(x+5) instead of +200x/x(x+5)?

She did it a bit unusually IMO (just take the longer from the shorter :tongue:) but no, the difference between the two times would have to be positive/an absolute value.

what does everyone think the pass mark for a 2 will be?


It should be around 50% for KU and possibly even less for RE

Just out of interest, what happens if you get 100% in both papers? I don't think I've got anywhere near that, but a friend told me that if you get full marks then the SQA send you a special letter. Is this true??

That's because i realised i was subtracting the longer time from the shorter time half way through so put some brackets in with a minus sign in to reverse everything - may have missed a negative on route :wink: Also knew it had to be a positive final answer hence the swapping :tongue:

It's 50% for nearly all standard grade subjects, and even for highers.

My sister got 100% for higher art (exam paper and met the highest criteria for folio) and the school got notified so she found out when she spoke to her art teacher :smile: so you will probably find out of you do! :smile:

Fairly confident! I think I've done better in Reasoning than in KU, don't know why :smile:

Does anyone think for question 9(c) on paper 1 that it's possible to pick up a mark even if you subtracted the wrong way around and got -200/x(x+5)?

That's the right answer, I checked invergordon academy's website.
I got it quite easily because I done the 2003 past paper which has an almost identical question :smile:

no it's positive 200 but I realised what you needed to do but just did it the wrong way, hoping for a mark

Same here! I wasn't too sure about paper 1 thought I had possibly failed it but now its looking more like a 1 or 1/2!
