I think i got between 74-86, I know its a B, its just the case of whether i got an A, I can just hope the boundries are low enough

Same here, I think I got around 78, which I'm sure is at least a B, but hopefully if this is too optimistic an estimation (say I actually got 70) then I hope the boundaries are similar to 2010, when they were 61!

I think i either got 98% or 99% very annoyed could have got 100%!! the question about finding cos theta- I found theta but then went on to calulate the value of Cos-1(theta) :eek:

I hope I only lose one for that! :frown:

as long as you explicitly said "cos(theta) = the answer" the examiner will disregard anything you put after that so you won't lose marks

Can you lose marks for not putting working even if you get the right answer?

WOW! thanks a lot for some reassurance, so there is a slight hope for 100% :colondollar:

An A probably cos last years was 61 and this was roughly the same standard so max boundary can be is like 65ish...how did other people in ur school find it?

I think people generally found it pretty hard... I got every question that I did as far as I can tell, but I thought there was way too little time! How about you/ your school?

yea...people found it pretty tough and there was the odd person who thinks they got 98 percent but i guess we should be fine regarding A's :biggrin:

Ahh good

... hopefully I might scrape an A then :biggrin:

How much will they penalise for not giving an 'exact value' but leaving it as a rounded decimal rather than in fractional/surd form??

This is what I put. I wrote root of 21 over 25 and then put what it equalled.

do u think the boundary will be lower than last years for an A

Yes. I thought that it was definately harder, and the A boundary will probably be a bit lower

The first question took ages!

If I got part 1 of a section b question wrong, and the following answers required the use of this answer, would they give me 0 or would they do that error carried forward thing and give me the marks if I had the correct method?
