It doesn't look like I'll be taking the 10g beta exam this time. I'm really busy at the moment so I've not got time to get ready for it. I've been doing some work:

I think my notes cover about half of the syllabus, but I don't want to rush the rest and try to fluke it. I'd rather wait until I'm ready. I'm aiming to sit it as soon as it goes to production. I think that will be about October. Hopefully by then I will have had enough time to get to grips with everything there.
If you are going to do it drop me a line to tell me how you got on.
