hehe was it flubber or blubber ?
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.

It was really hard! At our school we do Unit 5 before Unit 4 and there were loads of Unit 4 synoptic questions on photosynthesis and other stuff. The actual environment stuff wasnt bad! Did anyone else sit it?

I think it was a very straight forward paper in comparison to practise papers. I personally messed up the loop of henle question. But the dog question seemed ok to me. I mentioned how the dog has 2 cones instead of 3 and how the range of wavelengths of light is greater than a humans as it can see well past blue. I also mentioned how it has a better vision all round but the perception of distance wont be as good as our because the eyes dont cross over as much.

I think this paper will be a high score for getting an A. In range of (55-57)/81 I reckon.

did any 1 talk about how the dog only had 10 or 20% cones in central part of retina where ass humans have 90 to 100% cones at sentral part of retina therefore humans have greater acuity?

yes..for the 1 mark qs at the top of the page.
55-57/81 for an A seems too low. isn't an A around 80%?

no its ususually been in 51-55 but this year the paper SEEMED easier HOWEVER trust me there are loads of places to lose the odd mark, an example being the dog's vision and little bits here and there.

yeah, everyone who took biology 4 at my school (and trust me, there are some DAMN clever people) said it was hard/evil/nasty

oh well! I felt quite a bit of it was application and not knowledge

you need 80/100 to get an A which is 80% UMS
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

I found it realllly simple - Our 6th form has an annoying habit of teaching us WAY beyond the level we need - we learnt the eye from an oxbridge medical syllabus!!

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%

can some 1 explain to me all this raw mark and ums marks i dont get what u mean. i thought that you need 80% for and A which is 65 out of 80. i looked at all my last years exam results and i got exacly 80% in one exam which was an A. so how can it be possible to get an A with less then 80% i know that sum years they lower it or higher it according to the difficulty of the exams but isnt is always roughly 80%

an A is 80% UMS (ie the mark they give you on your results sheet) - this is not the same as your raw mark though. For example in an exam out of 60, often a raw mark of 56/60 will translate to a 100% UMS (ie on your results sheet it says 60/60). They standardise these depending on the difficulty of the paper so that it is always the same UMS needed for an A. For this reason, the raw mark needed for an A (ie to get an 80% UMS) can vary from year to year.
