Was it not the other way round as IIRC b represented the amount of money in the high risk account? -
Re: Ccea additional mathsi think i got it the other way around too! such a relief someone has the same answer as me!(Original post by quotidian)

Re: Ccea additional maths
Did really well in Paper 1. I think I only lost 2 marks, but Paper 2 was atrocious. I started to run out of time and couldn't think straight so completely left out the pulley question and screwed up the speed/time graph badly. In all I think I have lost about 20 marks.
Is it likely that I have lost my A*? What would ~170/200 be scaled up to?
AdMaths is my best and favourite subject so if I were to get an A rather than an A* I would strongly consider resitting it.
If I do resit, I have to do both papers again, don't I? -
Re: Ccea additional mathsYou can resit either paper 1 or paper 2 or you can resit both.(Original post by TheSilentFez)

Judging by everyones thoughts on the paper's I think the grade boundaries could be quite low. I'm near sure I heard someone saying that 45 / 100 in both papers was a C one year, so prehaps this year could be similar. -
Re: Ccea additional mathsI looked through the question paper (which I kept) and realised that it was only the pulley question which I really screwed up. I got all the answers wrong in the Velocity/Time graph questions because of one small error early on. I did the working out correctly for every other question, just using the wrong answer I got earlier. Do they give you full marks for error carried forward or will they penalise you?(Original post by ConorF)
140/200 was an A in several years. They will definitely be scaled down judging on the response from everyone here.
Generally if you lose more than 25 marks your A* is gone in Add Math. I am just hoping for an A now. Absolutely horrific two papers from CCEA this year.
If they give me error-carried forward marks, which I hope to God they do, then I have only lost about 14-16 marks. Add on the two marks I know I have lost in Pure and 5 marks just for unknown places I could have dropped, then I have lost 23 marks in total. Is it possible that I could just scrape an A*?
The A* Grade in a couple of past years was 171 UMS. Does anyone know how CCEA scale their marks? Would a raw mark of 175/200 be scaled down to 170 or lower? -
Re: Ccea additional mathsAll examiner reports, apart from the 2011 one, display the raw marks needed to get an A*/A or whatever grade you are aiming for: http://www.rewardinglearning.org.uk/...ions/index.asp(Original post by TheSilentFez)

Re: Ccea additional mathsHey silentfez, ive a similar problem to you on this one, i ended up with about 93 on the pure and 86 at least on the stats/mechs. I found them both really hard and considering i got 99 and 97 when i did last years papers as a mock thats a measure of how hard ccea decided to make this years. So the boundaries should definitely be lower than last year which were 141 for and a and 171 for an a* (ums)...but do you guys reckon 179/200 give or take a few marks would be enough to get an a*?

Re: Ccea additional mathsI got 100% in the Pure Mock and 94% in the Stats and Mechanics Mock, and I'm pretty sure I got 98% in the Pure Paper, but I completely failed the Pulley Question and lost 10 marks there. I also lost 3 in the inclined forces question and 2 in the Velocity Time graph question (they do give error-carried forward marks, don't they?) so at best, I have got 85% in that paper. I'll take another 5 marks off just in case and I have 178/200. I really really hope that is an A*.(Original post by conalltheconall)

Unfortunately, CCEA aren't good at explaining how raw marks are scaled up to UMS, so for all we know 178/200 could actually be scaled down to 170 or something.
Anyway, I personally think my predicted mark of 178/200 will just about scrape an A* in which case I will be relieved. If it doesn't, I will resit the paper next June, because AdMaths was one of the exams I really wanted to excel in (that and Latin)
Still annoyed that I didn't do better. I don't know why I couldn't do the pulley question. I took the question paper home with me and was able to do it instantly outside of exam conditions.
I'm normally very good at maths (if a little slow) so my pride has definitely taken a beating.
Oh well, I still have the capacity to beat everyone in my school at Latin

Re: Ccea additional mathsWith the pure I got everything right up until the log question then it sort of knocked me of course and i made 2 silly mistakes after which will cost me around 3 marks. I actually made less silly mistakes in the stats/mechs paper but I just cannot understand given that probability and I had never seen a standard deviation question like the one given. I finished 3rd in Northern Ireland in my maths GCSE last year!(Original post by TheSilentFez)

I can say with utmost certainty that our marks will definitely not be scaled down. CCEA only scale down if it was an easy paper, I don't know about your school, but in my opinion both papers were the hardest I've encountered so we should be scaled up, so I think raw marks of 170+ should be enough to secure an A*. But like you, I'm just gutted I didn't perform better/ -
Re: Ccea additional mathsYes, from the feedback I got, both papers were nasty so I think I'm fairly certain that a raw mark over 170 will be an A*.(Original post by conalltheconall)

So unless I have made more stupid errors than I previously thought (I hope to God I haven't) then I should just manage an A*
Nevertheless, it's still a disappointment that I didn't get 190+ as I was expecting based on past papers.
I still haven't done my maths GCSE...didn't get into the accelerated maths class.
It's this Wednesday. Hopefully it will be nicer than AdMaths. -
Re: Ccea additional mathsThanks! What about the last few parts of probability question?(Original post by KitKat123)
for sd i got 6.83 and mean 32.5 but i was prob completely wrong
