    Fingers crossed they are lowered, but I'd guess that an A* will be somewhere between 140 and 145. Most people found the exam to be fairly straightforward. Especially as the more difficult questions (sclera vs. conjunctiva, calculating the neurone speed, finding the anomaly, etc) only counted for a mark each (or maybe 2 for the neurone one).

    A* has never been that high before, it is highly unlikely it will reach 140. Averages have shown 133-135, so if you think it was an easier paper than it would more likely be around this kind of area.

    But, can't forget paper two. Need to see how people find that one before any kind of boundaries can be predicted to be honest!

    You may get this mark. but the correct terminology from revision guides produced by edexcel is 'receptor'.

    And an A*?
    Have done a couple of posts here on grade boundaries look back.

    Probably looking at 130-135 /180 for A*

    And 121+ for A

    Also depends on question aper two and how hard people find that!

    12. (Runners and Cyclists lower resting BPM Question) Adapted Red blood Cells Carry More Oxygen in oxyhemoglobin to body cells more efficiently for aerobic respiration. Heart muscles strengthen hence blood can be pumped with greater pressure and be maintained hence less heart beats needed to supply body cells with oxygen to respire = lower heart rate. (4)

    Number 12 is wrong. They don't have "adapted red blood cells" because haemoglobin can only bind with 4 oxygen molecules, not more - you can't change that through regular exercise. The answer is that the heart muscle is stronger as it is exerted more often, hence more blood can be pumped in the same number of beats, reducing the need for their heart to pump blood at a high frequency.

    This seems pretty valid, will edit now.

    Thank You!

    Yeah thats what I wrote, but the original guy who made the mark scheme wrote that so I just left it in, but yeah I agree.
