    Does anyone know where you can find past papers and mark schemes for B7? - it doesn't seem to be on the ocr website.

    Does anyone have any predictions on the B7 six markers? I'd love:

    Components of the blood
    Explaining why ecosystems are a type of closed loop system
    Anything on genetic modification/gene technology

    Haha, yes! If I was to plan some of these (after learning B7 right now) I'm thinking:

    Differences between Diabetes type 1 and type 2 and how they can be controlled
    Explain the components of the blood
    Explain the function of the heart and the valves in respect to blood
    Explain the components of a joint
    Explain different types of injuries and how they're dealt with (RICE)
    Explain what is meant by a perfect closed loop system and why ecosystems are not one of them
    Explain what is meant by a stable ecosystem and why their properties are beneficial (speak about vegetation)
    Explain the process of temperature inside the body
    Differences between vasodilation and vasoconstriction in the body and why they're important

    That's all I've covered in B7 for now - and I'm sure you'll have about a million of them!

    It's a bit off topic but:

    On the first P5 question (graph) I did a curve, rubbed it out (stupidly, yet telling myself it was just f(x) = x2) and drew a straight line. It was out of three marks and I was wondering how many marks you think that I'd get for:

    Straight line
    Not going through origin (since current started at 0.5A)
    'Current in Amps' on y axis, 'Power in Volts' on x axis

    These were the major things I think that you would've had to of included, so I'm thinking 2 due to the straight line that should've been curved.
    Seeing as it was a graph of current against power, I took it as given that 0 amps would produce 0 watts and so drew it through the origin. You can justify it either way, but I suppose they were just looking for the general trend. I reckon you should get 2 marks, maybe 1 if the examiner is mean.

    27 to 30, perhaps.

    And maybe any six markers for c7 and p7 too.

    what is there to say for 6 marks about why ecosystems are not a perfect closed loop system? All as i can think of is because of human activity e.g. Taking out unrecycled waste, overfishing and timber harvesting
    is there any more?

    Stating what a perfect closed loop ecosystem
    Why ecosystems aren't (migration of organisms, nutrients are carried by water/air)?

    Ohh i remember that now! Would you still put about the human activity?

    I know this question is rather far fetched but i can imagine that in B7 they will ask us aboit topics that arent on the specification, does anyone have any idea on what these could be? For example things youve been taught by your teacher which arent necessarily covered by the spec!
    i understand they could ask literally anything but its worth the shot asking i suppose

    Our teacher taught us about DNA ligase and DNA endonuclease in terms of genetic modification. We were also taught about tertiary groups and all of that ecosystem nonsense that I hate too. And we don't even need to know it!

    I hate when teachers do that! They seem to get carried away after teaching their A-level classes..

    Yeah I think it should be enough but c7 is quite hard so I would go in for any revision session your school holds because they have lots of calculations and equation but tbh My school didn't teach c7 good anyway :/ B7 is nice and p7 is just ok but then there's c7 lol. Good luck for your exams! Also I'm doing the same thing as u, I'm only revising in order.
    I'll probably still end up learning all of C7 the night before anyway

    There's been mixed feelings about the Physics exams. 123 could easily be 30 for an a* judging by how everyone seems to have done. 456 was marginally better, according to most people, but it seemed to me to be stuff that you could do if you knew the syllabus well, whereas P123 was just random crap for the most part.

    I actually preferred the P123 to the 456
