I've registered for the beta exam 70-541 for Windows SharePoint Server 3.0. I needed to ring up Pearson Vue as I don't think you can book the beta exams electronically.

Curiously, they didn't have "70-541" on their list, but they did have "71-541" which has the same title, and after a few tries the lady I was talking to convinced it to accept "BTA541" as the voucher/promotional code.

I have no idea if I'll pass or not, but since I'm in an exam-taking mood I thought it doesn't hurt to try, and I'll also be doing a fair bit of SharePoint stuff between now and January.
