IB blows itself up

They might as well have done. Apparently they have copied almost entire marking schemes from wikipedia. If they want maths marking schemes done, I will do them for nothing, as long as they send me the exam papers WELL in advance.
No doubt my IB students will be delighted to read I have made this offer.
I am waiting for a reply from the IB to this email:
Can I write the marking schemes for your maths exam papers?
I will not give the answers away to anyone I promise, unlike wikipedia who put everything on the internet.
