i do bio as well as senior science and my option was pharamceuticals - ur right. bio helps ssc so much! i went throught the exam with my teacher and she said that the picture labelled 'x' was an artery not a vein, but she said the diagram was very misleading and should be questioned.

You're probably right .. my whole class put a vein so i assumed it was right. i used erythromycin as my antibiotic too - but i thought that was a dodgy question.

It was a vein. The question was for 3 marks though .. so i'm sure if someone said it was an artery and compared an artery to a capillary correctly they will get 2 out of 3.

My school scales really well .. so i think that's why there was such a big jump - but im not sure how it works at other schools.

Don't worry .. a lot of people walked out not having finished question 1 because it was too difficult (well just the last part) Overall i felt it was a lot harder than previous years. Some questions were straight forward and i thought question 7 was among the 'easier' questions. 2 years...

unless is specifies .. which it didn't you won't lose any marks for it. if they were going to give you a mark for drawing a diagram they would, but seems they didn't say, they can't take a mark off. if they did take a mark off, they would be taking it away from another question as it's out of...

Thanx for putting up the solutions .. the answer for 10 b v) - the minimum area is 32(root)3 cm^2, but i don't remember part iv). Also with question one - ur calculator was in radians, so the angle in part d is wrong.. it should be 18 degrees (nearest degree) not 35 degrees.

it didnt ask for an area, just the integral and integrals can be negative

I could be wrong .. but a lot of ppl got -0.044. the thing is simpson's rule finds area, but the question didnt ask for area. some ppl still put an absolute value, but integrals can be negative and areas can't.

question 10 part a - the simposon's rule ... the answer was -0.044 (3dp)

I also got 32 root 3 as the minimum area. . it should be left exact but the question didn't specify so however you leave it they have to mark
