The percentage of people that died from malaria??


Posted from TSR Mobile


66.6% or 2/3 of the people who got Malaria

Are you sure you put braket?
How did I get 0.6%?


I think it was 3x10 power of 8
2x10 power of 6 but cant quite remember

2000000/300000000 x 100 gives you 0.6%

I know this is wrong because the apparently the question said animals, but if I put lichen for the last question, would I get the mark for correctly saying what they detect in the next part of the question?? Otherwise that's 3 marks I've lost for not reading the question properly...

also i wrote lichens to detect air pollution or sulfur dioxide concentrations and i wrote oxygen sensors to also detect air pollution

Well if you got an A* in your coursework you have a good chance at getting one if you do well in your exams. If you got a B in this exam then you will need an A* in another and atleast an A* or a very high A in the other exam to scrape into the UMS boundary for an A*. But anyways how did you find this exam?:smile:


That gives me a little bit more hope! :smile: Hopefully B2 and B3 will be different to B1. I personally hated this exam, thought some of it was irrelevant to the spec but I'm hoping I will still be able to get an A in B1 or, if I'm really lucky, an A*. How about you? :smile:
Could you say lichens and air pollution for the indicators?

Anyone wanna make a guess at the grade boundaries?

am i the only one who put 2/3 ??


You can't put a fraction as It asks for PERCENTAGE and secdonly AQA are trying to get rid of A*s to see who really deserves them sorry! So grade boundaries I think will be 50 for A*, no clue about the other grades tho

I put this as well. Doubt it's right (maybe one mark).

I *think* these are some other possible responses:
2) Just say the person gets addicted or similar - looking at past mark schemes shows this is the best 1 mark answer.
7) Because non of the bar charts show 100% of boys drinking (maybe also too small sample size)
8) All answers there are correct, but you probably only need to mention 3 or more for 5-6 marks
24) Foot is able to grip the ground (?)


Hm maybe maybe not you never know ..... it may not be the best but may be in that 'accept/allow' column :wink: At the time I thought it was an awesome response haha

Well, 2nd to last box was 'legal and medicinal drugs' and nicotine and alcohol are definitely not medical drugs. Definitely recreational drugs and legal. i.e. last box
For the last question, I wrote invertebrates and oxygen levels in water, would I get full marks. Invertebrates are animals, aren't they?

I'd say about 40 for an A and 31 for a B

Yes that's what I thought. I think many people mistakened second to last box to be legal recreational drugs in a hurry

Was lichen the right thing to put right at the end???
