What I think the Grade boundaries will be after some consideration and looking around at past reports ect ect..
13=D
20=C
28/29=B
37=A
48=A*
What are people thinking?


Like that, but the A* at 45 not 48. Because there will be some marks in that paper that very few people get.

What did anyone get for the question about: the first statements is incorrect
And the statement was like: mosquito larvae are at the bottom of the food chain for fish

Because the first step in the food chain is always a producer not a consumer.... Gotta be a plant in there somewhere
People keep looking fo answers when I offered to send an unofficial mark scheme (about 30 pages ago)

I believe the hypothesis was not valid as they only surveyed 100 or so people in one age group (15) so it was not representative and they therefore couldn't generalise but I could be wrong :/


sounds about right, i wish id put that but i think i wrote "girls drink alcohol as well" then at the end managed to scribble small sample size or something like that but who knows?

I'm guessing so, since it isn't an animal. Didn't stop me from putting that down though 😂

Wrong 0.7% because 0.666 rounds to 0.7 not 0.6

The only thing I can think of that isn't referenced in the spec anyway is the independent company question, which given you should know the meaning of the word independent (e.g. independent variable, independent event) could even be said to be in there at a stretch. Nobody's gonna have any trouble marking this paper.
Someone has shared this with me on Twitter - I hope this is the case for all of you :console:

"Where specific questions don't work as intended exam boards often exclude them so they don't affect final grade calculations. Statistical evidence will reveal whether any question can be regarded as a 'fair test' of knowledge (or not!)"

I put that none of the bars showed that 100% of boys consumed any of the drinks :// anyone say the same?

Yep. First bit asked you for an animal species, and the very very last bit asked you for a different way to survey the same thing. Since lichens detect air pollution and inverts detect water pollution, you won't be able to use them for the same thing.

apparently its 19 to get a C, so it would be less for an A* too. i guess about 30 +


Nope. Never.atleast 45+ for an A*
