    Its a new spec so there is only specimen papers to revise from. Thats why the grade boundaries will probably be lower this year as nobody knows what to expect.
    Or the paper might be easy - so high grade boundaries.

    Debatable - The paper might be easy (in terms of the questions) however the mark scheme can be extremely harsh when it comes to the usage of keywords. I was marked down for saying "amino acid sequence" rather than "specific amino acid sequence" in a question.

    Also, some have argued that because this is the new specification, the board might lower boundaries to make the spec more appealing, I highly doubt that however as I don't think it will sit well with Ofqual!.

    OCR AS BIOLOGY A (2015) - These puns are getting cornea and cornea...
    http://link.q.is/Pnwc/QvKOBHPGFt

    This is a quiz for Biology and it is getting constantly updated so it's really great for quick fire revision and good for practice of Multiple choice questions. Although its based from the OCR Spec, it's still useful for revision because biology is simply biology... So enjoy revising!

    The spec has been very vague about this. However I would still strongly suggest learning about WHAT asthma does (Smooth lining of bronchioles attacked meaning it contracts and extra mucus is produced, constricting the airways which cause wheezing etc.) and what impact it as on forced expiratory volume [reduces it so less air breathed out per second])

    And also how to reduce the effects e.g. asthma pump to widen (dilate) the airways by making the bronchiole muscles relax.

    Hope that helped.

    Thanks! Also, do you think that we have to learn about centrifugation of DNA molecules containg a heavier isotope to prove the sem-conservative model?

    Yes, we need to know about how Meelson and Stahn (However you spell it) did their experiment to prove semi-conservative replication

    I didnt know we had to know their names, just the principle of semi conservative replication.

    You don't need to know the names of those who were involved. Just the process that they undertook.
