I'm getting MCAS certified

[aestudiar]

Hi,
yesterday I got the MCAS prep book by Microsoft. I'm aiming to do the Word and PowerPoint this year, and hopefully the Excel and Access too (or at the beginning of 2011).
I'll start reading through the book, doing the exercises, and practising on my own.

Can anyone provide with recommendations regarding passing the exams?

1.- Preparation materials.
2.- Exam centres in the UK, close to London. Price figures.
3.- Once passed, what to do next? ie order the certificate from Microsoft? etc.

Many thanks.

PS I'm being lazy a bit, as I know I can collect all this info online, but doing 140 points at uni, the CompTiA+, SCJP, and now MCAS leaves me with little time. Thanks again.
