    Would improved sanitation and introduction of vaccines be acceptable for the factors which caused a decrease in death rate ?

    And yes, I'm pretty sure they're right

    The death rate went down. This could be due to an improved diet, improved sanitation or advances in medicine.

    The birth rate was greater than the death rate from stage 2 onwards.

    Both the overall population and the death rate were dashed lines, it was only one mark anyway

    I thought it was quite hard I know I got most wrong on the page about the heart. I also thought there were 2 correct answers for the multiple choice question about errors and time etc :/

    i thought it was hard too! what confused me about the heart diagram was that it was missing another set of valves and the blood vessels weren't attached to it! and also didn't know where to put the arrows!

    anybody know what the name of the valves were?

    Yeah I think it was

    I put that the tongue could be used to show verbal communication... but I'm really not sure if that's right, it was a bit of a weird question
    I put that all 4 were non-verbal signs, cos the tongue could be stuck out, eyebrows could be raised or frowned, hands for sign language, and i cant remember the other one??? Eyes? idk

    I mucked up the carbon cycle essay
