so frustrated that I'm going to post this again and again until someone answers PLEASE, don't make me beg.
SO annoyed. I made one teeny tiny error on 8c and got the wrong x.
seeing as 8d and e follow on from c's answer...how many marks would I lose for doing the correct method and everything just wrong values? Would it be :
1) all the marks for just getting it wrong 2) I'd get one out of two for each d and e for method marks or 3) error carried forward so wouldn't lose marks on d and e, just c?
I reckon your error will be carried forward, so only c marks lost. Unless they require exact answer for d, then you will lose 1 mark from there. For e it's proof that it's minimum so you will be OK
Can a triangle be a sector? Question 6d had odd wording in my opinion. PTQ actually forms a triangle...
Sorry, false. PTQ are simply three points. How they join up can be interpreted in different ways, depending on what lines join them, whether they're straight or curved.
It said sector PTQ, therefore was looking for the sector. If it meant triangle, it would have said triangle.

you will almost certainly lose the accuracy mark on d) you may get away with it on e) as it just the parity that matters not the value.
PTQ formed both a triangle and sector. Triangle if you use the straight line and sector if you use the arc. It asked for the sector therefore use arc and not straight line. Pretty simple really.
You reckon I would lose all 3 marks because I worked out perimeter of the triangle? or get 1 or 2?
I reckon your error will be carried forward, so only c marks lost. Unless they require exact answer for d, then you will lose 1 mark from there. For e it's proof that it's minimum so you will be OK
thank you so much !
I basically got up to 120/4pi for c then for an idiotic moment i seemed to think that equated to 30pi, not 30/pi (by the way, is that how you actually spell pi? LOL) so essentially i cube rooted the wrong thing to get a different x. other than that the whole method and rest of question was done right and accurately (up to that point).
I'd say one or two marks lost from c, possibly 3 at a stretch. what do you think?
I got EVERYTHING right but on the trig question I missed out the values of 90 and 180 (I got 0, 39.2, 141.8 or whatever), what mark will I get? 74/75? I really wanted 100 UMS I can't believe I blew it on such a stupid mistake. I drew the quadrants I should have checked it with the actual sin graph!
I had to read it 3 times to make sure that is what they wanted, seemed too easy for the last part of a question.
I don't disagree with you about it being easy (along with the general trend of this whole paper), although I disagree with the fact that people are trying to argue that it was poorly worded.

Could very well be just the 1 mark lost for c because in previous mark schemes they only require 1 part of working to get the mark. So for example if a working has 3 lines and you post 1 or 2 lines correctly then they give you the mark.
