Yeah, what about p3

p3 was compare the medical uses of ultrasound and xrays - you did the exam right??

This exam couldn't have gotten any worse. I literally was not prepared for any of those questions which appeared on the paper. I worked through radioactivity/radiation, parallel circuits, and mains electricity, and none of that came up. And then AQA asked us a chemistry question?! I mean I know people who are good at chemistry, would be pleased with that straight forward, six mark question- but when you're not some expert in chemistry, it's kind of a downer.. What did everybody else think?

I thought the 6 marker was a miracle for p2 and atomic structure has a lot to do with physics so I wouldn't call it a "chemistry question" but it did overlap with chemistry. Some of the questions were actually really nice. Just think how much worse it could have been without the little 1 mark questions to boost your grade like where does fusion naturally occur and stuff AQA wan't as cruel as they could have been. It was P3 I found hard :frown:

Personally, I found Unit 2 VERY easy. Unit 3 was a fair amount trickier Imo.

I got 9 for the half life question. You halve 40 twice to get to 10, so you should halve 36 twice to get the half-life :wink:

That's good, I'm glad you found Unit 2 easy. I sat all of my Unit 2's last year and got an A in all of them but I found the tests difficult...good job I had a whole year to revise just Unit 2 science! I thought Unit 3 was alright, it was easier than past papers but held its challenges. I'm really hoping for an A in this as I don't think I did too well in Chemistry and I want an A in Further Additional Science. :smile:

What did people put for one of the first questions in p2- you had to pick which line on the graph had the greatest resistance?

steepest one :smile:

Does anyone have any ideas for grade boundaries for A*-C in P3?

I drew a variable resistor not a resistor- will it still count? :frown:

Can anyone remember the wording of the 6markers (higher tier)

P3- compare ultrasound and x-Rays for medical uses. You should discuss the risks, if any, and the precautions, if any, for both.

Something like that

I put C which was the lowest line. I put C because the Steeper the line means the lower the resistance.

Don't think so because they are two different components.

Yeah, I put this and checked my revision guide and it's right :smile:

I rather stupidly drew a circle around my resistor, would that still get me the mark?

I don't think so because that's like another symbol

Um, if there's a resistor in there and nothing else apart from the circle around it, ye it may get u the mark.

what did people get for the movement of the wire in p3 (upwards or downwards)?

That is exactly what I said.
Do you by any chance remember what the labels on the axis were ?

I said Upwards.

What did people put for the half life?? I think I got 12 because from 80 I halved it 3 times to get to 10g, and then I diveded 36 by 3 and got 12 years?
