    Oh god. I got confused on the stupid mobile phone bacteria one. The simple table bit confused me. XD Umm I have never heard of Oedema coming up before this so that took me by surprise. The pregnancy one made me feel like I was just saying the obvious stuff.
    -The phone bacteria one was so random :/.
    -Pregnancy one, I understood the concept, but it was just so....weird and I didn't really think it was worth 5 marks FML . What did you write?!

    can anyone explain the question about the sodium chloride solutions and blood being added or whatever it was?!
    I thought it had something to do with Water Potentials and Osmosis, so I just stated the obvious? Didn't really understand what they were on about. Did you say anything about the precipitate thing formed? , I didn't understand what that had to do with it at all

    Haha same, im pretty sure I got it the wrong way around but said the higher concentration of sodium chloride had a lower water potential then the blood so water left the red blood cells through osmosis. didnt put anything else as i didnt know how to link it

    what were the questions on the mobile phone bacteria again? :confused:

    Absolutely hated that question, being honest...I kinda found this paper harder than the June 2011 paper :/.

    The bacteria one was all about Sterile stuff etc etc.

    I hope the grade boundaries will be a bit lower then. Barely did any revision for this so can definitely see myself doing retakes how is HBI02 in comparison?

    HBIO2 is my <3. Seriously comparef to this, HBIO2 is like, you can understand it and when you get something right. you're like **** YES!

    HBIO1 is hard, but being honest I revised practically everything and tried everything for HBIO1 and nothing could have prepared me for the sort of bullcrap they put into it.

    Ahh good thats how I find chemistry, everything is logical and makes sense. Have to actually remember all the processes in human bio, im really not good at that

    Most of them were useless as AQA didn't actually bother testing us, instead they gave us stupid questions....

    ^the real Human Biology. Seriously stupid questions, the hCG one, okay it was a good question but tbh...for 5 marks, should have really been 1/2 max :/. what do you think you got? Marks wise? . The grade boundaries better be low. :/

    Yeah such a waste of time learning the cardiac cycle etc. Probably about half if im lucky haha, definitely worst exam for me so far, you?

    This exam actually took me by suprise lol For the NaCl question I wrote that the higher conc of NaCl made the solution more hypertonic so water moved out of the cells by osmosis down a concentration gradient. It turned a straw colour because the blood plasma is straw coloured and all the cells had been taken out of the blood by the centrifuge. To be honest, I have no idea how the pellet was larger in the higher conc of NaCl solution as I would've though the blood would've lost more water making it shrink. The pellet size confused me, it seemed backwards . The pregnancy test was about monoclonal antibodies and just saying how they work, no idea how you can get 5 marks from it but there we go. The mobile phone question was so random the only thing I could think to say was they were concerned because the bacteria could make her ill, they had multiplied rapidly etc etc. To be honest I weren't happy with my overall performance :/

    Actually, it was to do with Pressure. It was to do with Sodium Chloride Being A Salt and salt causes High blood pressure and then that does something to force water (Or whatever it is) into tissue fluid causing Odema ( I think). I Wrote about water potential as well but who knows, there may be a mark for it. Its only when I was walking out from the exam that I realised. I Only ever seem to remember everything towards the end of exams. Still, they may lower these grade boundaries. At least I hope they do

    I am pretty sure it had something to do with water potential considering the question previous to it was the definition of Osmosis? idk.

    hCG is explained a little in the Nelson Thorns book for As and it is mentioned on the AS spec, but still was unfair :/

    The NaCl one, that's what I thought! It must have to do with something to do with Osmosis since the question previous asked for the definition. I guess anything related would be fine :/

    It mustve been water potential because the whole section was on osmosis..

    Yeah i just cant see the link between "Pressure. It was to do with Sodium Chloride Being A Salt and salt causes High blood pressure" Maybe I just did so bad that it's left me mentally screwed and im talking crap
