It was great for me! I'll stay away from discussing what did and didn't come out, but it was quite easy but quite perplexing.

I am finished with the AS! I'm celebrating today and tomorrow by not studying anything at all.  :P

Baby, it ain't over till it's over.

I mean the results, FYI. :>

It was good. :)
I made some silly mistakes myself. Wrote lysosome instead of vesicle, etc. Maybe because I didn't sleep so well.  :-\

Haha, were you stressed about the Biology paper? For which question did you write lysosome instead of vesicles? Cause there was a question concerning with what is the role of the lysosomes in the phagocyte, so if you used lysosome there, you should be fine...

No, not that.

I am talking about the one after the labeling.

I also did a silly mistake on the calculation of biomass or whatever.

Furthermore, many other silly mistakes in the xylem question. >:|

The labeling part.. Wasn't it the Vacuole or tonoplast?

I wrote a huge random answer.

I just remember I wrote "After breaking down the organic compounds and forming raw materials like N2, their cells absorb the N2. This gives them energy".

omg same here!!! i don't know what's up with me while doing the paper.. i plot a curve without the constant line..  :'(
so i obviously dont get marks for explaination of the constant line too.
what really scares me about this paper is that each question has like 3-5 marks..
and for some questions i'm not sure what do they actually want us to write  :(

what the...

It isn't facilitated diffusion...? O.M.G FAIL >_>

I am pretty sure the question said "It is 1000x LESS concentrated inside..." so is it really active transport?
