    for the last one I put alpha and gamma because it started off at 250 and went down to 140 when it came into contact with paper then it went down to 20 when it came into contact with lead. but the other 3 I put as only 1 radiation each
    Thank god i wasn't the only one who put a mix down then xD. Can't be worth a loss of that many marks can it? *~*

    7b: Paying for electricity.

    Uses 1.5Kw for 20 hours so 30KwH x 18 = 540 pence [2]

    I thourght it said 0.5 hours for 1.5kw of power so i got 1080 pence

    Wouldn't it have to be 1.5 kWh not just kW for it to be the energy supplied in the time? The power of the appliance is independent of the time of usage unless combined to calculate energy supplied ?

    yes! 0.5 hrs was just a mean additional thing put in by ocr. it doesn't change the current or voltage so wont change the power so 540.

    You will probably not be safe with 52/75 for an A*. It was a much easier exam than previous years.

    That is true. However, the grade boundaries dont really ever change. From Jan 2012 to Jun 2013 they remained similar, then they were upped for June 2014 and 2015 and there was no real change in difficulty. I predict about 56 for A* but could be lower. Definitely wouldn't go into the 60s.

    Yeah, you'd need above around 56 to be safe, and I certainly did not make that.

    I can't tell without a worked through mark scheme,
    Although I'm the most pessimistic person ever, and physics is the one exam I need, could be a correlation here:badger:

    Lol whenever i use markscheme i always mark harshly so for this i literally thought if i fail all the 6 marks (18 marks gone) i can still get an A* i did really good as im looking at others answers which is the smae. I hate physics but found the paper good
