    Am I right in thinking we don't need to know how to work out standard deviation?
    Don't worry. The text book specifically says that you do not need to know the formula for standard deviation for your exam, it is only used for the coursework. For the exam you'll just need to know what standard deviation shows and use it to talk about the data.

    What is the best answer for the question: What is genetic diversity?

    I know how it's to do with the variation of alleles, but what exact words are best?

    Thanks!

    OK, does anyone actually know what the UMS system is all about? I was under the impression that 80%, 65/85, was the lowest mark that you can get to get an A? but from what people are saying here, it seems like its actually a lot lower? I dont understand the AQA UMS converter thing either, i got 78% in my january unit 1, and got a B, so i re-sat it last week, but Ive done past unit 2 papers and the converter says that my marks, that range between 64 and 73 out of 85 are all As?

    SOMEONE HELP?!
    im an AQA examiner for bio2 this year and A grades before are normally minumm of 55 out of 85 for an A on average!

    they effectively add 15% more to wat u actually got

    Hey everyone, i've just stopped revising, my brain literally can't take any more information. Hopefully its all in there somewhere

    I really really really hope there is a 6 marker on:
    DNA hybridisation, genetic diversity, fish or insect gas exchange or antibiotic resistance. But as most of them have already been done i doubt it oh well, nothing wrong with a little wishful thinking :/

    I absolutely HATE chapter 17, chaper 7 and the end of 13 (plant stuff) oh and all the common sense type questions - i just can't think straight in an exam.

    I think it is the number of differernt alleles posessed by individuals that make up a species

    It's just really annoying and then the answers are really weird. Like "why do you have to repeat the experiment?" Sometimes the answer is to reduce the affect of anomalous results other times the answer is to identify anomalous results. What the hell at least be consistent AQA.

    I find unit 2 so boring. I hate plants and learning about how science works. What you need is good proper human biology. The heart, lungs anything like that is interesting.
