# Let's make an unofficial mark scheme for 2016 AQA Level1/2 Certificate Biology Paper1 Watch

1. I found the chemistry test easier that normal so I think that the grade boundaries will be higher than usual since all people in my school found it very easy.

For the polar bear question the working out goes like this:
2.3-1.4=0.9
0.9/1.4=0.6428...(a)
a*100= 64.28%
Yeah if those are the correct lengths, that's what I worked out. I just did
(2.3/1.4) * 100 = 164.28...
and then I just subtracted 100 to get 64.28% as well.

You must have a good memory to be able to remember those lengths!

Yes mate that's right
4. yeah. The polar bear was 2.3cm and the sun bear was 1.4cm. I got 64 as the answer and it can't be 39 because - if the bear was 50% longer than the sun bear, it must be 2.1cm however, the length of the polar bear was more than that so it has to be more than 50%!!!!!
5. Continue
6. For the carbon cycle question I put respiration, photosynthesis, eating, decomposition and the explained them.

9. How do you draw a curve of best fit? On markscheme it says dont do it dot to dot, but how can you not? its almost always clear that its a curve so how can you not do it dot to dot?
