Elective csect as KKH subsidised patient

Hi. I would like to know any experience from anyone here going through elective csect as KKH subsidised patient on how the process when you admit yourself to KKH as in do the doctor let you know which date to come or you admit yourself till there is available slot for you? Keen to know about this cos I am giving birth there in 2 weeks time as previous doc told me when there is a slot only I can proceed. Please share with me. Many plenty thanks!
