I have no idea, think different school will act differently. may need to check with the school on how the balloting going to be conduct.

BTW are you intending to go for PV at RGPS?

I just send my PV registration form to RGPS, and received an email, stating they will contact me for interview in April. Will it be possible to share with me what and how the interview session going to be like, and is there anything that i should be aware or prepare myself before the interview. Thank you
