LOWER by atleast 1 or 2 marks.

Yh i think they would be about 30marks to get A* some people actually did the question that was wrong so i guess they might need to compensate for that cuz ppl might have wasted time on that.

Wasn't everyone told before their exam started? I was.

Im not sure some one in this post said they spent 5 minutes on that question, maybe they weren't told.

Not everyone was told apparently :s-smilie:
My son had the exam stopped half way through to tell them.

I doubt it lol. I would have liked that too :tongue: results day is just round the corner though!
I didn't do this exam but the people who did it in my year didn't get told about the dodgy answer until the exam was finished... looks like the OCR boffins have screwed up big time! :rolleyes:
We was not told about the dodgy answer but I knew something was up with it ¬_¬ And what did you guys put for the one about what all EM waves have in common under certain conditions?

I wrote they all travelled at the speed of light (3x10^8 m/s) in a vacuum. What did you write?

our school werent told and i spent about 10 minutes trying to get my head around the question then i just guessed eek :/
I thought the exam was reaaally easy... XD
I think the only questions I had to 'guess' at was the EM spectrum question about the property they have in common (I put they're all transverse and all travel through a vacuum), the question about the reflected rays to the microphone (I drew straight lines bouncing off but smaller) and the ticky box question about why did the microphone not pick up much sound (I ticked the one that had something to do with one wave journey not being in step with the other).

Other than that it was very straight forward...
The first question was a joke. Foundation level! XDD

And half of the ticky box/choose the answer for the blank questions were so stupid as there was only 1 answer it could possibly be as the others didn't even have anything to do with anything! XD

Was question 9b ii) wrong because the X wasn't on the line?

Um i think the tick boxes choices they gave us was wrong or what u said the x wasn't on any line.

What did u put for the question was is it about a bad idea to measure the amount of acid using pH? (something like that)

Yeah, to me the X looked like it was floating, so not actually marking a point so maybe this would've caused confusion?

Hmm, I can't really remember the options :frown: I think it was quite straightforward.

This threw me a bit:
The response has X to the stimulus. I said it has no direct connection but this could have been debatable. They didn't say whether they meant the primary stimulus or secondary one. It would have no direct connection to the secondary stimulus but the response (salivating) does have a direct connection to the primary stimulus.

So yeah. If you know what I mean?


OMG That was what I was thinking: I put true for that one, but the primary stimulus was the food and I thought that the response (salivating) DID have a connection with it :frown:

See, someone did share my confusion.
They should have stated whether they meant primary or secondary otherwise it's down to interpretation!
