    What does the specification mean by this:

    The benefits for sustainability of processing waste polymers by: (i) combustion for energy production (ii) use as an organic feedstock for the production of plastics and other organic chemicals (iii) removal of toxic waste products, e.g. removal of HCl formed during disposal by combustion of halogenated plastics (e.g. PVC). HSW9,10 Benefits of cheap oil-derived plastics counteracted by problems for environment of landfill; the move to re-using waste, improving use of resources.
    How different processes can be sustainable/unsustainable. You need to be able to know the processes and how they work along with their overall sustainability compared to each other. In regards to plastics benefits and limitations of them being 'cheap' such as made from crude oil which is a finite resource and how waste can be processed and have second uses.

    Anyone's got any tips for time management for the depth paper?
    60-75 seconds per question? Try the sample and practice paper under timed conditions?

    the grade boundaries for chemistry would be about 52/70 for an A
    47/70 for a B. well that is what our school told us, because for the new spec papers, we have to learn everything for both papers whereas before it was split into two which was much easier
    for biology people are saying it would be about 47/70 for an A. the thing is ocr needs to make people carry on with biology next year so grade boundaries would be lower 68% for an A. it was like that before with the old spec too which was easier so dont worry guys there is hope

    mechanisms will be on there i hope but pv=nrt is unlikely

    i would say the long answer questions would be on organic chem mainly so revise it more

    do the long answer qs first and then do the short answer questions

    I think i got 58-62 would 58 be an A?
    Yeah. I think I got about the same around 60/70. hope the depth goes well too.
    I love checking unofficial mark schemes on the student room cos i kind of know how well i did before results day

    not really, because we dont know how pedantic the marking will be yet

    it is true tho. the mark scheme for the new spec is so specific . say a question is worth 6 marks there are only 6 bullet points in the mark schemes. but the old spec had a range of points that could be covered.

    Nobody has got a copy of the breadth, since it has to be used for mock exams next year. But i have no idea how there are proper unofficial mark schemes for maths. but arsey no longer writes them like the proper ones with the questions and answers

    There are answers to the breadth. The paper with answers were posted on twitter. Although some of the answers are wrong

    Mass spec and IR
    Mechanisms
    PV=nRT

    any others?

    Teachers have access to paper...
    But they won't post because OCR doesn't want them to
    Oh and proper unofficial mark schemes are from teachers who have access to paper
