    Since it said something like "In terms of the artificial...." I assumed the structure would be something like this...
    "Artificial heart valves are the best option as they have been in use since 1960, which means they have been tested and will work efficiently. Whereas, human heart valves have only been used for (i forgot how many) years."
    I just did 4 points with that structure, I hope its enough for six marks!
    Okay, I just did advantages and disadvantages for the artificial heart valve and backed up my points, I made points about 3 advantages and 3 disadvantages with a slight comparison in the shortl conclusion so hopefully that's enough for the 6 marks.

    iirc it asked for advantages and disadvantages of the artificial heart valve compared a human heart valve, so I compared every time I wrote an advantage/disadvantage

    That sounds like plenty for six marks, although I don't think you'd need to conclude as it only said to state the advantages and disadvantages and not to compare or what not.

    Wait what egg question?! Did I miss a question out?!
    There were 2 different exams. Both had most of the same questions however one question was different. I think it depended if you are doing separate or triple science. One question was on eggs but on the other paper it was on the diaphragm. I know it confused me too!

    What did everyone put for the question with the bell jar model of the human ventilation system? I was really stuck on why the 'diaphragm' flattening caused the balloons to inflate, I feel like I should know this but I was stumped!
    I put that the diaphram moves down so the volume in the jar increases, which decreases the pressure to less than the atmospheric pressure so air is drawn into the jar! U3 was fine compared to that EVIL U2 paper though!

    fairly sure it was to compare the cow heart valves with the living human heart valves??? and it gave all the info in a table???

    Like how for human you had to cut open the chest but for cow you just put it in blood vessel in the leg

    Cow heart valves? I really hope you didn't say that on the paper! It was definitely human heart valves vs artificial heart valves.
