Edexcel B: Global Challenge

I was just looking through some past papers, and they always have questions on weather & ecosystems and Population & the economy.
So I was thinking, would it be worth just revising one topic from each? Say weather and population/migration?

What does everyone think?

I would say thats far too risky as you could be unlucky and there wouldnt be a question on what you wanted.

Id say its safer to revise it all, but with some bits in more detail if theres a topic youd like to answer on, e.g. migration and hope this comes up, but dont bank on it coming up!
But i suppose it would be fair enough to miss out one or two small topics you dont like, for example im not revising el nino as if there was a Q on this i wouldnt answer it, but i am revising the rest of climate etc.

So id revise more (even if its just breifly) to be on the safe side to be honest!

i would advise revising most topics as sometimes one of the questions is really nasty. and if you only revised say weather, and that question is very difficult then you have no back up

But weather ones are fairly straight forward normally.

Anticyclones haven't come up for a while. Biodiversity is a very current topic too.
For the Human I'd suggest Population / Demographic Transition and Globalisation winners and losers
For Cross-modular I'd look at Poverty, Sustainability and Millenium Goals

Our teacher says you can miss out small topics such as the ecocline, but revise all four topics thoroughly so you always have a "nice" question to answer, as you'll know your stuff. I hope the location of ecosystems comes up, and a really easy question on globalisation as I don't really get globalisation, but we haven't really covered population as much. If that made any sense to you at all :biggrin:

Hey everyone, hope the revisions going well. Has anyone got any past papers? If anyone has, could you possibly type out a few of the questions? I would be greatful forever, and obviously rep. I have no past papers except the mock we did at school. I could put up those questions if anyone wants them. I thought about only revising two of the four topics too, but decided it was too risky. The main problem I'm having at the moment, is that I don't have a decent book to revise from. I've got the heinemann revision guide for edexcel b, and its ok, but I really don't think its detailed enough. The AS one was great but the A2 one insn't so good. Anyone got any suggestions of other books that are good? Thanks. :biggrin:

I would suggest revising it all, just in case a tricky question came up on the one you had revised!!
And Marvi ive dug out all the questions i can find, most of them appear to be the nat environment or cross unit, cant seem to find my old pop and economy notes.

Thats all the ones i have which dont ask for figure numbers...hope they help :smile:

Good luck

What's 'a mid latitude deoression'?

Near enough to hurricanes. But they cannot call them hurricanes, typhoons or willie-willies because they do not form between the tropics. They are just depressions that we get in the UK etc.

Thanks dans!

They are areas of low pressure which occur in the mid latitudes, as dans said we get them in the UK :smile:

They are basically weather systems which bring cold, wet windy weather!
And i didnt mean deoressions, that was a typo :p:

And thanks for the rep :smile:

Willie-willies? :p:

What are they in relation to weather & climate? :p:

Willie-Willies are what the Australians call Hurricane's. In the Indian Ocean they call them Typhoons and in the Atlantic they call them Hurricanes. In Oceania/Australiasia they are Willie-Willies.

chris 135...i've been thinking bout doing that, simply cos i dont hav enough time to revise al the topics due to other exams.
think im gonna revise both pop&ecomony for human side but for physical side im only gonna revise ecosystems, cos i just never got the hang of weather and climate, even tho its meant to be the 'more stright forward one' :s-smilie:

i know its not the ideal thing to do but i dont hav much choice!! :frown:

someone mentioned only revising one of the weather/climate, ecosystems and population/migration topics...but that wont work because you need them all or at least two for the last question in the paper that is going to be synoptic surely?

Well that's certainly true but as long as you plan your cross-modular answer carefully and ensure that you cover all 4 aspects somewhere along the line you should be able to cope. You can always focus more facts and figures on the areas you DO know about after all.

when you do use knowlage from other modules in the cross unit question do you need to say that or will the examiner pick up it?

What do you mean? like writing "i know this from the ecosystems unit"? I think thats a bit of a waste of time, the examiners arnt stupid, aslong as you know it and answer the question why does it matter...? :confused:

Yeh, do you have to make it blatantly obvious that you have used information from other units? Or will it be inferred just by the fact that you know it.
