Higher Maths 2012

Thanks, hopefully I pick up some marks. I cannot for the life of me remember what I did for 5b so I'll just presume I lost all marks there, I'm borderline A at the moment depends on whether they bring the A mark down, do you think they will?

B around 73-75 out of 130 this year do you think

See for the drawing the graph ones i drew parabollas for both, i presume 0/6 marks?

I guess it depends on where your turning point was. It it was, for the first graph, at (0,0) or (2,0) you may pick up a mark. If the transformation of flipping over x axis and moving up by 2 is correct for your first graph you will probably get 2 or 3 there

5b was nasty I got completely thrown by it. I'm guessing that if you brought in root 3/2 and tried to make some head way you'll probably gain a few marks. I hope they would but comparing other highers to maths, maths always has quite a high a mark. It might be brought down to the 69/70% zone or possibly a bit lower. There is no doubting most of paper 2 was a/b grade questions.

nope, i moved it down 2 i totally messed it up, think that probably cost me my A :'(

I wrote down root 3 over two haha! And I also multiplied the 2 at the bottom of the fraction through the k bracket, hopefully what I did will get me 1/2 marks and I'm really disappointed with 30//40 on MC! If it stays at 75% I'm unlikely to get an A but if it lowers to around 72/73 I'm in with a shot! I agree it was mostly A/B questions which is very unusual I'm sure it's normally about 45% A if not lower, so they should lower the A mark even by a little, I hope so anyway another quick question see for the wave equation question in paper one I recall finding out the two values for cutting the x axis couldn't get the y, but I did it in degrees, do you reckon I'll get 1/3?

how many marks would you get for not making the 30 root3/2, but still rearranging the equation etc?

I'm guessing you may pick up 1 or 2, just depends how far you got into the reordering

You'd probably get at least 1 but my teacher told us that they are becoming really harsh when degrees is used and not radians, although it usually doesn't amount to more than a couple of marks off.
Good luck come August 7th, I can just see future years looking back on our exam and saying '2012 is clearly the most difficult paper ever, glad I didn't do it'. Just got to hope the SQA adjust boundaries to ensure its still a fair exam

Paper 2 solutions are attached. I did this quickly so mistakes might creep in. Do tell me and I'll correct them

Please link to this post rather than the file itself so the link is always to the most up-to-date version.

EDIT: Paper 1 solutions now attached as well.

ahhh when i click it to open it just dissapears, can someone post photos pleaseeee?
