If the boundary is 80 for a 7 and you get 79.5, then you will be considered to have achieved a 7.

Oh, if this is true, then I've been under the wrong impression. I got the notion that the IB did NOT round our scores - as in, they took both our scores and the grade boundaries to a ridiculous number of decimal places. So even if you got 79.4 and the grade boundary was 79.45 (reported as a 79), then you would miss out. At least, that's what I've heard from students in prior years and in my year at school.

But then again, I hope I am proved wrong. I would love to be rounded up into a 7.

My interpretation (which may be wrong):

If the sum of the components gives an overall of 80.5% for a 7, the boundary is 80%, whilst if you get 79.5% they'll count it as a 80%. So you'll get a 7 even if you got 79.5% instead of 80.5%.
