    Question 5 from which paper?
    i mean the last question, which is usually based on the isert pre-release (it's usually question 5)

    Done them all except Skill V (interpretation)

    What marks did you get in them? What kind of questions came up in your Skill V?
    I got 10/12, 10/12, 10/12, 11/12, 12/12 i think skill 5 was all about ionic equations / half equations on halogens. LEARN OXIDISING POWER of halogens

    Ah. So we have info on all 3 shots for Skill V. Mine one will be about Group 2 elements, specifically Calcium. Thanks for the info man.

    Looking at the specimen, which was also on PR stuff, id say it could ask to draw a monomer of the plastic and have a question asking to explain how the properties of this plastic make it sutible for what it us used for and also I would guess that it would ask for another use of the plastic. Most of the time, if not all, there is a long 6/5 mark question. Guessing here, it will probably ask about the different density polymers, or it could ask about the formation of polyethene.

    Hope that may give an idea

    These are ideas that I had about potential questions too :yy:

    at the bottom of page 2 there is a reaction involving a radical and ethene, does anyone know what kind of reaction this is?

    At first i thought that its homolytic fission but i am not sure now.

    Now i am thinking it is electrophilic addition. does anyone know?

    It's radical polymerisation - which is not on the syllabus so you aren't supposed to already know all the details: http://en.wikipedia.org/wiki/Radical_polymerization

    ahhh ok. do you think they are likely to ask a question about this?

    Also has your teacher been through the article with you? Mine hasn't ! :eek:

    Aren't the uses of polyethene already in the article? do you think we would have to extract them from there? Also by properties do you mean flexible?

    Thanks!

    Not sure what they will ask, but do revise the topic of radicals and the topic of polymerisation.

    I'm not a student, but I think it's quite normal for the teachers to not go through it with you.

    Best advice i can give is print off the syllabus and go through it with a fine tooth comb to check you know everything on there and then you should be fine. here's the link: http://www.ocr.org.uk/download/kd/oc...d_gce_spec.pdf

    We have been tought F331 & F332 so badly. The teachers have just skimmed over every topic, and we still have one or two more things to learn!!.

    So yeah, you could say I'm bricking it for the F332 exam especially. Any tips on how to revise all the content, because there certainly is a lot of it! I suppose I'll be doing a lot of past papers as well!

    same, in my last few chem lessons, our teacher has made us play games using memory cards to remember the different alcohols (ethanol, methanol etc.)

    anyway, i would say memorise mark schemes because the same questions come up in nearly every exam paper. It really helps when it comes to the 6 mark questions.

    I find go over the spec helps a lot.

    Yeah most likley with reference to the article, however from doing past papers a good amount of the 20 marks you can do with your own chemical knowledge

    Can someone please tell me all the reagents and conditions for all the reactions in our spec that we need to know!!!! Would be a massive help!
