    achieving 65% is pretty good, i haven't heard of anyone getting anything higher, i got 61% in the secret practice paper and i will do the public specimen paper today and see what i achieve, I'm really worried about biology i was hoping for an A but these specimen papers have removed the remaining hope i had in me.

    What is Chi Squared And The Hardy-Weinberg Equation. I havent been taught this? Also whats the difference between paired and unpaired student t-test.(I doesnt say any of those ^^ on the specification for AS so I don't think its gonna come up, maybe its next year?)
    We are technically supposed to know how to do them for all modules, however as you said things like Hardy-Weinberg almost certainly won't come up on AS papers as the content for it isn't taught until A2. It may be worth having a quick look over how to do them, though, just in case they're feeling sneaky.

    Chi Squared is fairly straightforward and is used to see if there is a significant difference between expected and experimental results. I'm not sure why you weren't taught it as it is applicable at AS.

    There's not much maths questions but you can probably do those in the past papers I've seen although it might be difficult to try and compile them because of how little there are compared to essay and short marker type questions.

    You're best bet might be to look at textbooks, online and other workbooks. You might be lucky and they'll compile the maths questions in one chapter or something. If not, maybe try and look the formula up in the glossary. They usually put the questions on the same page where they wrote down that topic.

    You mean the practise papers? The second set of new spec papers? Some users might have it but usually only the teacher has it because only they have the access to it. If you can't ask them, maybe look at biotutors, I've been hearing some rumors that they kight have the second set of practise papers on their list.

    Good luck though

    I got 66% on the practice, I get my result for the specimen tomorrow.

    The only way to get good at maths is to practice it, which is quite difficult to do with such a lack of questions unfortunately.

    Nope, you just need to know what they are and possibly give some examples Name:  XSPFcq.png

    I'm so not ready guys. Who's going to fail with me!?
    Specimen papers WAY too hard!
    I cry when I see them. The older past papers on the previous spec are much nicer and easier.

    I average around 55-60%. Why is it our year?
    First year for rising tuition fees
    First year for new A levels
    Second year for linear GCSEs

    I KNOW! It's everything. Every single thing has been made harder for us.
    But this new spec is a Joke.

    I'm interested in how the exam board sets the boundaries. Surely, the same amount of people need to get A's each year? So if they make the paper as hard as the specimen, the grade boundaries should be as low as 50%.

    Have you seen how the old spec was written? It basically tells you every detail of what you need to do while ours is just 'show an understanding of a microscope'.

    I'm pretty sure you do need to know the advantages/disadvantages for both- the specification is too vague, and the advs/disadvs are in the text book, so I would learn them if I were you.

    Not tryna scare people but it's very likely that the exam on Thursday is going to be very difficult...OCR need to prove in this new spec that only the most capable get the A's, not the people who learn it all without a good understanding.
    OCR are moving away from just simply writing down theory answers; they're are going to want you to apply your knowledge to hard situations involving complex practicals.

    I'm really annoyed too that they have not given any good resources at all....just 2 papers really?? and the 2 secret ones...
