    My school has 3!!! I win!
    D'awww :C I was close! Mine has 4. 3 males, 1 female. There was a grand total of 5 last year! The one who dropped, on a COMP1 mock exam, did the binary addition of:

    100
    100+
    = 200

    I think you can guess why he dropped it.

    What is likely to come up on Tuesday do we think?
    Anything and everything, tid bits from each aspect of the spec.

    We have something like 4 A2 classes, so that's about 60-70... and I think there's three A2s who are female. It's very concerning and there should be a push to make more women feel comfortable taking STEM subjects

    Then use,

    Cool thanks, appreciate it! I've actually seen the first video, but that was before I knew about hashing

    I think it is gonna be hard to tell what's going to show up, considering this spec has only been used for 5 years. I guess the sensible thing is to assume that what hasn't shown up so far is likely to appear. Those are my thoughts anyway!

    Not just that but AQA are incredibly skilled at screwing students over. Don't be surprised if you see a wild question in the exam.

    Can somebody tell me the third normal form saying, something like, '...the whole key and nothing but the key...', but there's more?

    Every attribute is dependent on the key, the whole key and nothing but the key.
    I think that's what gets you the marks in the exam.

    I was doing the Jun11 paper and the question asked "what is the smallest positive that can berepresented using normalised floating point system."
    I put 0.0000001 with exponent of 1000, but the markscheme says 0.1000000 with exponent of 1000 - anyone know why?

    Wikibooks agrees with me :-S

    Thanks in advance!

    A Normalised floating point must have a 0(dot)1. It can't be a 0(dot)0.
    (I maybe wrong, if so please correct me)
