Hey Deon,
I dont know if they would be only interviewing non CC for your VRD. My VRD was a mixed bag. i don't think there would be any reason to seperate CC and non CC but anyway... let us know if that is the case.
Try not to rely on these books, ect. Use them as a guide but remember the recruiters have interviewed 1000's of people and they will know which answers are fabricated. As i said, be yourself and honest.
First aid should be fine. I am doing mine this weekend too.
In regards to when you will hear form them. I heard from the 7 days after the VRD. Nothing special, just letting me know i have made it passed the VRD onto the next round.
Hope this helps and good luck.
Maeson.
