here's the email guys:
info@ofqual.gov.uk
This what it says on the website:
You should include:
a clear explanation of the nature of your query or complaint

your centre name and number (school/college/training provider)
the name of the awarding body/organisation
the qualification or unit title and code number
copies of any relevant supporting documents.
We will send an initial acknowledgement within 2 days of receipt of the complaint
A substantive response to the complaint will be sent within 10 working days. If this is not possible due to the complexity of the investigation you will be notified and kept updated in progress. -
Re: Aqa a2 chem5 19th june 2012Some people have done...(Original post by kookyuke)
are people complaining to ofqual?? because we can over that MNO4- question
Apart from that, the exam had nothing that was unaccheivable. The problem was that there were too many questions which required a lot of thought, and the time spent on these impacted on other questions. Basically, if we had had more time, we would have been able to think enough to at least make good guesses! I didn't even have chance to check my work, and a few of my calculations were wrong. That's cost me 5marks to start with. The wordings were vague too, and the exam caught a lot of people (including me) off guard because it was so utterly different to ANY previous paper. I think AQA should have had a specimen paper with application of knowledge questions on, which would have at least got us being able to get used the style of questions, because we have all adapted to the simple recall ones.

Re: Aqa a2 chem5 19th june 2012i got this using the ratio they gave us(Original post by nicolemonica)
I used 3:5 ratio and got around 97%, I haven't heard any one else say they got this so hoping that's not 5 marks gone! did anyone else get around 97%? -
Re: Aqa a2 chem5 19th june 2012I know the worst thing about the paper was the HSW/application questions when all of the past pspers were pretty much recall(Original post by Matthew692692)

Re: Aqa a2 chem5 19th june 2012Except the initial mass was 1.8g so it is over 100%(Original post by Notsocleverstudent)
Also there was definitely not a fault with the ratio they gave. The moles calculated to something like 3x10^-3 and multiplying it by 7/3 than multiplying it by 10 gives 0.1 moles and mass is something like 2.6 something grams. So 2.3/2.6 gave something like 70%
EDIT: Some people have said 1.381, I forgot which, but even then, still over 100%Last edited by TheGrinningSkull; 20-06-2012 at 09:44. -
Re: Aqa a2 chem5 19th june 2012Exactly my point! Half of my paper was guess work. The only section capable was the colour of transition metals but then again they didn't make that easy as past papers! I don't know what was going through their heads when they wrote the paper!(Original post by IamBeowulf)

Re: Aqa a2 chem5 19th june 2012You mean as a catalyst? It usually is an ion....(Original post by bubbletrouble)
Does anyone remember how man marks the last question was, the one about Cobalt acting as an ion.
It was worth 4 I think- 1 mark for the equation, 1 mark for the explanation thing (I can't remember what they asked), and 2 marks for the half equations. -

Re: Aqa a2 chem5 19th june 2012Haha I meant catalyst, I had just woken up when I wrote that lol(Original post by Matthew692692)

Re: Aqa a2 chem5 19th june 2012I know the style was completely different from other papers. I opened the paper expecting a nice Born Haber cycle question(Original post by jayy1994)
Exactly my point! Half of my paper was guess work. The only section capable was the colour of transition metals but then again they didn't make that easy as past papers! I don't know what was going through their heads when they wrote the paper!
And I almost forgot to put the reagents for the TM question -
Re: Aqa a2 chem5 19th june 2012X as a fraction of Y is X/Y, not Y/X.(Original post by Notsocleverstudent)

Re: Aqa a2 chem5 19th june 2012lol i put the same as you but the gradient value i put was 0.1, dont knw if thats right though(Original post by rlaekdnlt5)
For the graph i didnt work out gradient but put j/k/mol and delta s. would i still get two marks? And how many marks was the percentage mass question including ratio?
-
Re: Aqa a2 chem5 19th june 2012sorry mate, thats wrong!(Original post by chris669)
for the last equation I used o2+4h+ +4e- = 2h2o, would I still get the marks for this? -
Re: Aqa a2 chem5 19th june 2012apparently that's right(Original post by sachinisgod)
lol i put the same as you but the gradient value i put was 0.1, dont knw if thats right though

i didnt even know how to calculate the gradient

Re: Aqa a2 chem5 19th june 2012
I wasn't going to bother posting here because I didn't want everybody panicking like I am over this exam. Im on a gap year because I found out today last year my Dad had cancer which was a day before the June 2011 exam and I didn't get a chance to sit this exam in January because my Dad passed away a week before my exam. This is my deciding exam which I have spent 3 month preparing for and was extremely hard and completely different to what was from past papers.
I hope the grade boundaries are lowered and from everybody I've spoke to they've all found it extremely difficult including somebody who was moved up a year in 6th form because he's a genius ha!
As for the paper regarding the spec as much as I would love to to kick off about stuff not being on the spec it was all spec work
The problem with the paper all questions were up to at least C standard and higher every time there was not a good range of questions.
For everybody who has got this far, the reason I I didn't originally post is because I had a copy of the paper 10 mins after the exam and thought it probably be best I didn't post it on here straight away but I will post it soon as im at my computer. I'll have to take it apart and scan it in
