    I found this on the AQA site, don't know how reliable it is though, looks pretty solid. http://www.aqa.org.uk/exams-administ...t-marks-to-ums

    Bear in mind that this mark scheme doesn't include all the marking points and additional guidance that the official one will, so you probably got more than 30
    Cheers, I'm not sure though. I wrote silly things like Modern ventilation was more expensive, and the Iron Lung was claustrophobic!

    Can only hope, would be disappointing if I don't get an A

    For question 2 part 4 (advantages and disadvantages of positiv pressure breathing systems), would i get a mark for saying that it allows freedom of movement, unlike negative pressure breathing aids?

    I calculated I could get a minimum of 51 marks, is this an A*? I really need to know because I need an A* to get an A* overall

    The predicted grade boundaries are under the mark scheme in the original post...

    EDIT: Yes, you would get an A* if you got 51

    If the climate is dry there is a higher concentration gradient from the skin to the air, if the air is 'humid' there will be less of a concentration gradient if not none therefore no/less evaporation. myGCSEscience mentioned it in one of his videos.
    Lol. Not everything he puts in his videos are on the specification. Search that on the spec and it's no where to be seen. Evaporation rate is only linked with Hot, Dry and Windy conditions. That is all you need to know. what you wrote would not gain you an advantage over what I just said...

    You could well get the mark for claustrophobic! Also thats only two marks down
    I got out of the exam and panicked a lot because i thought i hadn't done well, but i eventually realised that i was only remembering the hard questions/ ones I hadn't done well in. Just think of the positives and get working on your next exam!

    I never said it would gain an advantage over your answer, I dont know about the spec but both of my biology teachers have said it'll get the mark and if he's putting revision videos on the internet for the current spec then why would he put stuff that isnt on there...?

    I didn't say you were wrong dude. I'm just saying that the person from before who said that we wouldn't get the marks for putting what we put is wrong. You'll get the marks, it's just the extra info was just a tad unnecessary, but hey no harm in learning more than neccessary

    i would have thought that a* boundary would be lower becasue the questions in the paper were mostly application based. so aqa are likely to say that because the paper was hard then people with high marks would deserve an a*. It isnt just about percentages, its also about if the candidate desevered an a* or not. So example would be that the exam paper was really hard but a lot of people got good marks then say 10% would get a*. But then the next year the exam was really easy and a lot of people got rubbish then 5% would get an a*. AQA have specified this many times in the past.
