To get an A* you must get an A at As level
Not true. You can get a C or higher at AS.
But you must get above 90 percent in a2.
If you get a c at AS, then that's almost 100 percent on all A2 modules to get an a star!

Why did they get the bacteria from different patients??
I put something like different bacteria have different resistance
and to to compare them
I said large sample so data is representative... o.O

No you don't: you have to get 80% UMS overall and 90% UMS in A2 units.
You can get 70% average at AS which is a B, but get 90% average at A2. This would be an A*.

I put similar, but just mentioned that it may have been a mutated strain which contained some resistant bacteria.

Edit:

First part I thought was representative sample, the other part was where I answered as above when it talked about hydrachorite (or whatever it was) being less resistant in the other hospital.

The question specified water moving from the endodermis to the xylem to the leaves. I believe the apoplastic and symplastic pathways are from the epidermis towards the endodermis? So for that question, marks would have been awarded for the key words such as osmosis of water, the lowering of water potential and water potential gradient, root pressure, cohesion tension theory and the evaporation of water at the leaves.. stuff related to that and not the pathways.
I agree

That paper was so weird, felt as if on opening they had put some sort of trippy acid on the pages O.o

I can draw better chromosomes than that and I'm about to fail Biology.

You were supposed to talk about apoplastic and symplastic pathways
root pressure is involved as well because, it says pulls water up the xylem

For the 6 marker you were only required to write about the movement of water from the endodermis to the leaves, you did not need to talk about apoplastic/symplastic/casparian strip, just root pressure and cohesion-tension.
Yes I'm confused why everyone is talking about the pathways.

I talked about root pressure and cohesion, although I did mention symplast pathway.

Rounded to 342.9 =l

Hopefully we get ranges.

I reckon that was one of the hardest papers I have seen in a while for unit 2.
I think I got it, except for 1 question I couldn't answer! DX

1 marker on why are homologous chromosomes are not genetically identical!

Thank you I was bricking it when people were saying that as I was sure it just required root pressure and cohesion

You don't have to get an A* at AS at all.
A* requirements say that you need a 90% average over A2 and an A overall, meaning that you can get a B at AS and still get an A*

Omg! The amount of revision i did for this stupid exam seriously did not reflect the paper i just sat. What the hell even was that? I think aqa need to realise that just because we do biology does not mean we have an avid interest in animals such as snakes. Seriously, i think i've hands down failed. I was getting A's on past papers and now i'm just thinking lol, where's the vodka at?
