Clickable IB Guide

Wikipedia has a revision guide which is worth looking at if you're bored with some time to kill (or have IB exams coming up!)

Real GDP

For the year 5s who are trying to work out real GDP for different countries:

Find a list of figures of GDP for the last few years, e.g.

2000 - $100 billion
2001 - $105 billion
2002 - $110 billion
2003 - $115 billion

We can work out from that the percentage increase in GDP each year
e.g. $105 - $100 = $5
$5 /$100 x 100 = 5%

However, these are only nominal statistics. We need to combine these with the inflation statistics - we minus the inflation rate from the headline figure to get the real rate of growth each year.

Multiply these figures by the first year and you should get a set of figures for real GDP. I know that sounds confusing, but it should be relatively easy in Excel. What it means is that though at first you seem to get a set of figures with growth of:
5%
4.9%
4.8% etc

once you minus inflation from it it will look like:
3%
2.9%
2.8% etc
(those figures aren't precise)

Then you can times those by each year:
$100 x 3% = $103 billion
$103 x 2.9% = $105.9 billion
$105.9 x 2.8% = $108.9 billion

Hope that makes sense.

More Past papers

Though I'm not uploading the mark schemes, there are some more past papers at the link below.

If you can show me you've done some work on them, then I'll give you the mark scheme for them.

Have fun

Past Paper Mark Schemes

I have now uploaded the mark schemes for the past papers below which can be found at:

Don't just try to learn mark schemes, though. It's not that helpful. I will also upload a set of papers without a mark scheme which, if you bring me some work on, I will be more than happy to give you the mark scheme for

IB Revision Guide...eventually!

Hi All,

Many apologies of course, but I figured out why the revision guide from the library wouldn't upload - apparently I can only upload up to 20 MB files and this is around 80 MB. If I emailed it to you all, many of your email providers would reject it also.

With no more excuses, I will tell you that I've uploaded it onto sharebigfile.com. You'll need to enter the code at the bottom of the page and click on redraw to get the file. If that's causing a problem, just bring a memory stick and I can put it straight from my lap top onto it.

Of course me posting this will mean I get to see you all tomorrow still, won't it...

Mr W
