    NOT HAVING A GO HERE but their objective is not the 'catch you out'. Their objective is to differentiate the candidates who have done proper hardcore revision and know all the info and how to apply it from the candidates who just skimmed over the subjects. In all honesty though, I have for suuuure failed this!
    LOL!! That was very much in the heat of the moment but they did have lots of one markers though and some were tricky - You have to agree. Like the ones about calculating heartbeat, it was difficult to differentiate whether the cycle was 0.7 or 0.6. And the one about how they got the number of deaths from each ocuntry blah blah blah. And theyy had poorly worded question too!

    Totally agree with you on that. Lost all them calculation marks + the 6marker was vague so i forgot to talk about mitochondria etc, but if it asked specifically about mitochondria in a 2mark question, i woulda talked about atp \: ... jheeze.
