I know this a bit of topic, but how did you do in maths? I'm so worried about it. Did so bad :/
Aw don't worry about it, grade boundaries will hopefully be low & looking at mark schemes makes me feel optimistic because they give you marks for the smallest things. Um overall I think I got 170 and hopefully a few more other marks..

Also the diving question I didn't compare it withe the fizzy bottle. Will I get marked down even though I includes the points ToLiveInADream said?
If you didn't compare it, what did you do? As long as you included bits from the box and drew conclusions, it should be fine

You did amazing! I got about 130 :/ I'm so disappointed because in all the past papers I was getting 80+ until that exam :/ I'm worried I won't even get an A now :/

Yeah I included everything you pointed out and talked about the pressure which is kind of linking it but I didn't actually compare the bottle with the water and I remember it said compare so :/

I messed up the insectide question I put about interdependence and how a reduced number of insects will mean less food for other organisms rather than bioaccumulation
I get how this is wrong if you use insecticides it will kill insects and that is a food source. Removing food source affects other organisms(the question) because they will find it harder to survive and can starve :confused: I put about accumulation, interdependence and then related it all to a perfect closed loop system and how insecticides is like removing outputs and inputs so the ecosystem and hence organisms in it are affected, I also put about ecosystem services and how you are affecting plants because insects can pollinate (plants are organisms right?) So plants aren't fertilized as much, and knock on effect with food here

I found it really vague and initially had nothing to write and ended up with an essay

Did anyone mention bio accumulation for the insecticide question?

Also I put that the process involved in tissue fluid was the exchange of molecules (e.g. Oxygen & glucose)

There was a question where you have to name the system in the glasshouses. Was it negative feedback?

That question had me looking at it for a good few minutes! I don't allow myself to move on without answering but that's what I got in the end it was a part b to the question about temperature so I'm pretty sure that's correct unless theirs another system to do with temperature control...?
