I signed up for the BCP-610 course using my 1/2 off code from last year. You have to pay for the cert as part of your registration for $75 or use your half off $150 through Prometric. The WES 2009 testing site is available now but the good times are going fast.
If you sign up as part of your registration, RIM will send you the code for Prometric then you just make your appointment and put in the code. Either way, you make the appointment through Prometric.
