No problem...
btw how was chem P4??

Organic part was so hard. Left 8 marks straight due to lack of time in that.
Rest of the paper was fine. But i'll be losing marks here and there. Hoping for a 75+
How about you?

is oxygen in plasma? as it stated another substance in "plasma"
i wrote ions.... and then explained facilitated diffusion for it.

I guess your answer is right.... i guess my one is correct as well... check the link below:

lets just pray that our answers are right in the marking scheme

Cud anyone please tell me that for example there is a question for 6 marks and they tell us to describe some process (in biology) .... would we get all the 6 marks if we write minimum 6 valid points or do we need to write the whole process step by step? In mark scheme they have written max 6 marks and also they have given some 12 steps. Will we get 6 marks if we write atleast 6 of the steps or is it compulsory to write all the 12 steps one by one to gain whole 6 marks?? Please help.
Thanks in advance.

6 points and you get the marks.
Write 7-8 btw to be on the safe side.

The paper was not easy. So I hope the threshold is low.
1) Tertiary, tertiary
2) Lung cancer, chronic bronchitis (not sure about this one. I did bronchitis cuz of wheezing). Here's what wikipedia says.

3) I did 3 and 4, it's wrong. It's supposed to be 1 and 2.
4) I did xylem is lignified option. I don't think mass flow occurs in xylem.
5) I chose that oxyhaemoglobin has no effect.
6) 1900
7) I did option A that discs produce spindle. Can somebody tell me what option C was? Like the statement? I don't think I read it properly.
8) I did yes yes yes for decomposition nitrification and nitrogen fixation option.
9) There was an ecoli ribosome? Really?
10) Temperature and unsaturated lipid option
11) It was at lung sth right? I did HCO3- ----> H2o + CO2
12) Paper 22 was soo hard :'(

1- I did the same, its correct, from a past paper.
2- messed it up,
3- which Q is that???
4- dont remember
5- I think I said the same
6- yup
7- dunno
8- same
9- ?
10- same
11- same, I'm almost sure that's correct
12- I agree, hoping the gt for that is 40-42. It's not unheard of.

For my MCQ paper, I can't see the gt being higher than 31, really hope it's not. Did you do paper 12?

no. 2 is totally confusing. Although i chose the same option as yours, if you search google about emphysema or chronic bronchitis and compile symptoms of each from 2-3 websites... all the ones given in options will be covered for both. So this is an MCQ which's answer we will know only when the marking scheme comes
