    I think adding another cable would interrupt the flux cutting of the first cable, so emfs would be enduced on both and so it wouldn't make a circuit. Not sure if this is the exact reason, but it's definitely something to do with a second cable also cutting flux line
    Yeah that sounds about right I think

    Does anyone know what the flux loops look like? e.g. question 3a here

    Is it true for anybody else that most of their peers and friends finished their exams last week, whilst your still wallowing in work for tomorrow?

    Goddamn I've barely looked at the anm since I did the questions when it was first released.

    Nearly all my friends finished either friday or earlier, I've had FP2 today and then this tomorrow to finally end my 11 consecutive exams.

    Lets just say I'm going to be getting very drunk tomorrow

    Luckily for this year, all the topics appear to be based on stuff we did in A2 (chapter 11, chapter 18 and chapter 15) and not anything to do with AS topics because I don't remember anything from last year

    Has anybody been doing section C of the past papers by any chance? If so, how does the difficulty of the questions compare to section B?

    It's 100% useless to do Section C in the past papers, but bear in mind it's worth the same amount of marks.

    Ouch, even worse then haha.

    It's a silly one-touch space arcade game that'll be on sale for ~£1.99. I price it that way because I hate in-app purchases.

    You can check out the silly trailer for it here: https://www.youtube.com/watch?v=OK79RO_ev9s if you want!

    Haha I'm glad you liked it. I would release it on IOS too but being lisenced IOS developer costs like £200 up front and like £100 a year, that's cash I don't have haha. Damn it, Apple.

    Not necessarily. If you have fully completed revision and have went through this years pre-release, doing some section C questions could be helpful to prepare you for the question style in section C

    I don't know about that, I think you can get a very good idea as to the kind of questions they'll ask by practising predicted questions, and by just reading the wording of the anm.

    E.g. it's almost certain they're going to ask where the energy for tether power comes from because they basically wrote "This is not energy for nothing, though", but never explained why.

    I think we can agree to disagree, but I consider doing section C a waste of time.

    Does every college have a different set of preliminary questions for the advance notice materials, or are these shared between institutions? If they're not shared I'd urge everyone to post them here so that we can get a nice bit of practice for section C!

    (sorry that it's a word document)
