AQA (B) biology 4 Watch
i thought it was ok generally, but a few questions i was unsure about, such as the dog's vision
haha..and the flubber qs was annoying..didn't like it at all.i thought it was harder than past papers i'd done before but i attempted every qs.
for that one the graph showed that the deeper you go into the blubber, the warmer the temp is so its shwoing how heat is being conserved within the blubber.
for the next part, i wrote about homeostatic mechanisms and how the arterioles contract when it is cold so that blood doesnt flow in the blubber etc=less radiation blah di blah.
Did anyone do Unit 5 - The Environment?
i was supposed to do it, but backed out last minute..how was it?
I think this paper will be a high score for getting an A. In range of (55-57)/81 I reckon.
55-57/81 for an A seems too low. isn't an A around 80%?
oh well! I felt quite a bit of it was application and not knowledge
what other hard questions were there i cant remember?
the raw mark which corresponds to 80 will not be 65 I guarentee it. It is usually around 50-55 but I think perhaps this paper could be 57 for an A. However you can lose marks so easily you cant judge your performance to accurately like you can for say maths.
the dog question comprised of a 1 mark and a 6 mark question
The grade boundaries are always that low, I got 90/90 and 120/120 in two of last years modules and the raw mark of them was only around 85%
