Is there anything that's AS related that you could write?

The only one I can think from the top of my head is Immune response

The 25 marker questions are designed to test you on how well you can link biology knowledge together, so there has to be some AS topics you could talk about.

You could talk about the immune response, something along the lines of more antibodies being secreted, hence more pathogen/antigen gets destroyed. Something along the lines :s-smilie:


Don't worry too much about AS linking since these questions came from quite a while back, when the spec might've been slightly different. I searched up online, there's this hormone called Erythopoiesis, which is in the kidneys that signals the bone marrow to produce red blood cells when there's not enough oxygen in the body.

Apparently that wasn't for some weird reason I had seemed to think so too, seems a bit obvious as well, but its supposed to be something to do with the fact that its just a 'defense mechanism'. so long as the case can be justified i guess. :confused:

Osmotic effect too.

What about refractory period, do reckon that'd probably be one?

Strictly speaking, negative feedback is where an increase in one variable causes a decreases in another variable. Maybe variable, ain't the correct word, but you get the idea, right?

I dunno about refractory period, I personally would try to go for another topic, because you get marks for essay breadth, they want you to chose something from each unit (ideally)

If you can, try and go through some ISA questions. That's a good way of practicing HSW questions.

Learn how to answer 'evaluate' questions. You have to give a for and against view. Generally more against than for.

The answers tend to be like, 'not tested for long enough', 'small sample size' etc.
I need to do quite a bit of revision of the AS topics. I've never done a resit of any of those modules so I haven't looked at them in a while. I no longer have an AS textbook, I had to give mine back to the school library as per the rules at my school. I'll probably buy another, which would people recommend? A revision guide-style one would probably be fine, it's not like I'm learning everything from scratch (I have all of my notes in a box as well). Needs to be relatively cheap though :colondollar:

Yes I am, I'm the one who had a bad experience and changed instructors :colondollar:

Cheers, I'll try there! My friend has the CGP A2 book and that's pretty good so I'd be happy using that.

I have sat the A2 ISA papers and not done too well. I got 33/50 on the highest scoring one. I was wondering whether I should do the Empa instead. I have never done the Empa before and so was wondering whether it is hard or not and if I should enter myself for it. Also, would it matter if I have ISA submitted for AS which I resat this year and for A2 an Empa which would be submitted this year

you won't be able to enter for the A2 EMPA because you've already done the A2 ISA

As long as the A2 ISA has not been submitted you can do the Empa
anyone done a mock ? If so what sort of marks have peeps been getting?
Anybody got any good sources for further reading? or any methods to pick what to further read? For the essay Of course.

Theres so many things that could be asked and so many things that could be further read, not sure how to go about it :/
