It is not even funny how bad i did on that test, my mind just went blank and i started to panic. I think there is a high chance i won't get any marks on the last 4 pages; which is annoying as when I came out, i remembered and could explain the answers to my friend. My hope for an A overall has gone out the window.

Sorry for the long post.

Tadpole was stupider to be honest! But yeah, i got 8 then (8/25)*100 = 32% ??

Ahaha, everyone just hates that tadpole now (myself included!)

I didn't know how to explain how I got to it, but 7 and 28%?

What did you guys get for the calculation question with the graph.

0.67 I think,

Can't believed I screwed up the one about veins and arteries. I put arteriole....that's some marks down the drain already.

What i believe i got:

Heart 4/4
Stent 4/4
Capillaries and Artery 4/4
Ventilation – graph 3/3
Ribcage and thorax 3/3
Artificial lungs - 2/2
Advantages and disadvantages – 2/2
Food chain – 2/3
6 marker / intensive farming – 5/6
Active transport, osmosis and transpiration stream – 6/7
Water and leaf- 3l4
Tadpoles - 3/5
Athlete- 5/7
Glucose- 2/5

= 48/59

Sorry to burst your bubble but you wouldn't have got 4/4 on capillaries because it asked about blood composition not the difference between the arteries and veins in general

Anyone put structure x on the stupid tadpole question because of a thin wall?? To maximise diffusion by increasing the rate of diffusion because substances have a shorter distance to diffuse??? Everyone else seems to have put surface area, that question was so confusing , I'm so gutted I didn't finish the paper

I can't believe there was nothing on the kidney or dialysis I was so prepared for that eventuality!

How did everyone work out the calculation question as well? I did not have the foggiest idea and I still don't know now :/

Same here!! Well, I worded it stupidly, "thin skin" but you get the gist. I ran out of time on the last q, that one tripped me up.

I put oxygen then stupidly changed it to minerals then proteins (thought about what made you grow) then I think I left it as minerals?? Wish I just went with my initial answer of oxygen that's what everyone's said it is

Well i first did 210 divided by 30(minutes), which equaled 7 - which they gave you, so I then did 310 -210 and got 100 which I divided by 150(180 minutes - 30 minutes). Which equaled 0.67.

Reading this back, this doesn't make sence - sorry if I havn't helped you.
