    Me neither? Just a question on drawing it? The question beforehand was about a similar thing with the light bulbs though maybe it was that
    What lightbulb question?

    i got A* in my ISA
    around 50 in P1
    Around 30 in P2
    Around 35 in P3
    Do you think I can get an A???
    Even if you got the lowest possible A* in your ISA, (44 I think - ??) you would still average around 70%, which could even be an A* after those dreadful Unit 2 and 3 exams.

    Realistically, what is the highest the boundary could be for an A*? Many saying mid-40s, but last years was 47 and you don't see grade boundaries decreasing a lot, they tend to rise.

    What lightbulb question?
    It had a diagram like this, and the question I think was something about the effect of moving one of the light bulbs further/closer to the lens?

    Yep I definitely didn't get that question. Probably a different spec?

    last year's grade boundary for further additional physics was 41 (A*) and for chemistry (triple science) it was 44. where did you get the 47 from?
    i think its gonna be 38 for an A*

    last year for chemistry, 39 was an A* but in 2014 it was 47 (see how much it has decreased!) so why cant it be for physics this year?

    There was the question on the foot pedal and drums. You had to find out the force of the chain from the foot pedal (3 marks)
    It said there was a 1.5 N force from toe I think. 0.20 from pivot to the chain. 0.12 from pivot to toe.
    What did you all get for the answer?
    0.9

    I got 0.9N as the force for the chain.

    So I can get an A?!

    One of the questions asked you to draw the correct symbol for an ammeter and in the correct place in the circuit. I got the symbol right definitely however I don't know if I put it in the right place - I put it on the right of the circuit.
    Just 1 mark by the way.
    Did it no go around the cell?

    The ammeter is connected in series I believe, so it has to be directly attached to the wire.

    Ah, I drew a line going up next to the cell, across and then the ammeter symbol, and then continued the line across and back down to the circuit, would that be correct?

    If it's like this, then this is correct:

    'Why is X-rays not used with unborn babies?' (3)

    X-ray causes ionisation (1) which are damaging to the foetus' cells, causing them to become mutant and divide uncontrollably. (1) This leads to cancer. (1)

    This question also came up in the 2013 paper, which I took last night. But that time they gave you 2 marks, whereas this year's paper gave you 3 marks for the same question...
    You would also have to say why ultrasound is used, which is because it is non ionising
