Hi! I hope everyone is prepared. I'm feeling pretty good about this exam. I hope someone releases an unofficial markscheme after, they help loads! Good luck everyone!

[Oglogski]

Found this qutie hard. Probably <40/60 for an A. Not much higher.


or maybe this was just me?

[ninuzu]

Yeah A LOT of people in my school found it hard, so hoping for low grade boundaries.

[master y]

So bloody hard

how did u find it??

[LauraMuser]

I found this so much harder than any past papers I'd done, realised I'd gone 4kw too high for the 'one cup' kettle question /: Didn't really leave myself enough time for the question on the polarising filters in 3d glasses, found it unusual to see that question on significant figures, but I guess it was an easy mark, overall though I don't feel happy with how I did /: Does anyone remember what they put for their estimate of strain on an elastic band? o:

How can they 'help'?

Maybe its nice to confirm your 100% but for most of us it ruins our summer ;P

Good Luck.

I'm also feeling quite bad.
Hopefully we'll be saved by:
1) grade boundaries have been as low as 34/60 for an A on this paper. That's about 50/60 for full UMS
2)The paper is only 30% of the AS. Can still be pulled up massively by the other one (which is easier and 50%) and coursework


I put 5 (a 5 cm rubber band would stretch about 25cm?)

[aidanatkin]

I found it really hard as well, all the emf questions I counted up the ones I was confident on and I reckon I got about 43/60 I hope the grade boundaries are OK

I hope so, I haven't spoken to anyone who's been totally confident on this exam, so I really do hope the grade boundaries are low.
And true, I hope the second paper isn't as difficult >.<

Actually that makes sense, I put 0.5 imagining it not to have stretched that much o: Oh well
Good luck for your results

[aidanatkin]

I put 0.5 as well, I assumed it'd stretch just over double its length which is about 2 times and so closer to 0.5 than 5 maybe they'll be a bit lenient, I hope so!

[LauraMuser]

Yeah, me too!

[Ashlee93]

That's the third time i've done this exam and once again I don't think I've done well, I should be aiming for a high B/ A but I just found that was really hard,

[HeatherEssex]

I've never done so badly in an exam in my life. Was predicted an A but admittedly I didn't do loads of revision but I would be lucky to get an E, I would be ecstatic if I got a D after that. Need to revise like crazy for next friday

[Ashlee93]

so what did people put the the kettle one and the strain on an elastic band one?

also the resolution, diameter thingybob, what did people get cause i'm 99% sure I did it wrong :/

[Fruippe]

For those of you who put 0.5 strain on the elastic band, I looked at the 2011 past papers and some on the questions in there indicate 5 is a much more likely answer, although it does vary a lot - maybe they will be lenient..

As for the kettle, I put 50.. is that correct?

[_typo_]

For the elastic band/kettle one I put 0.5 for the elastic band and 5kw for the kettle. If you look online most kettles tend to be between 1 and 3 kw therefore 5 is kind of in the right magnitude and as for the elastic band I would expect it to stretch by less than twice its original length - certainly nothing like 5x - and they wouldn't be the same answer surely?

[Ashlee93]

typo - i put these answers too - god i'm stupidly stressed out about this! What did you guys put for the galaxy resolution, light year one?

[Ben_055]

I couldn't answer the galaxy one, i forgot how to work it out :/

[Ben_055]

How did you guys work out the "Voltage Drop" ?
