I've seriously bombed paper 2

Woo 11 marks Roughly I think I got about 45 out of 70, added to about 55 out of 60, so 100 out of 130. Enough for an A? Certainly enough for the B I desperately need.

The only chance I have left of passing is picking up random marks...

Cheer-up Allan, SQA might decide to be generous. I think the majority, or whatever half then haven't done as well, most people in my school walked out in the second paper after an hour.

see for paper 2 on question one when you have to find the angle, everyone else(and in the marking scheme written by someone) used the magnitudes but i did it by using OP and 0Q then the dot prodcut of those two over the magnitudes. i got Q wrong in part b so obviously that meant i didnt get the right angle, but since you can only get penalised once i think maybe if my method is ok i wont lose the full five marks. does anyone know if thats an ok way to do it or not?

thanks--im really annoyed as i found the paper difficult but now looking at the answer schemes i seem to have actually got some of the harder ones that and done stupid things on the easier ones like this^ i mean the other way is so much easier and obvious. owell if someone could tell me if that way is a valid way that would be good!

thanks

**Edit:**Paper 2 now available too!

Hope you like what you see!

Would it be possible for you to put up a copy of the actual paper if possible? Int2 and AH too If possible please

I used the fact the we know the gradient at Q is 4 so i said the Gradient at P will be -4.

If the gradient is negative -4 then x - 8 = -4 therefore x = 4 and the y-coord is the same as Q so the point P is (4,10)

Please let me know if this makes any sense and if i would get the mark for it.

Thanks alot.

Think that's how I did it. Same answer and I'm sure it's a valid method. I was aware when I did the question that there were other ways of doing it.

You really are obsessed, aren't you John

The Int.2 one was...what word shall I use...fun?

Probabilities rock!

Hi, rest easy! You should not get penalised for 'correct' working following an earlier error. However, if you made the solution easier, akthough in thos question unlikely, then you may not get full credit from that point. If you follow the link on page 1 of this thread that page also contains SQA marking schemes for 2005 & 2006. In them you will find the guidance given to markers on how to mark papers and see how questions are marked.

Does anyone know in paper 1 the circle question basically I had no clue how to do it and just did the obvious found the centre and the radius - would this be worth 1 mark?

Thanks

No can do John, sorry! Copyright.

We have very quick scribbled solutions for Int2 but will be putting up a neat copy as soon as possible.

IMHO it was a VERY straightforward exam, much easier than this years Credit yet worth more UCAS points. Go figure?!

We did not have anyone sitting AH this year so we don't have papers to make solutions for. Might get some from another school in due course.

There are often one or two different ways to solve questions, particularly those that involve more problem solving.

For example, for P2 Q5© we thought of about 4 ways to do it but picked the one that we thought came closest to 2 marks. Most we thought involved more work than 2 marks seemed worth. For example, working out the point of intersection of the normals at P and Q, as someone suggested earlier I think.
