Ditto...

Just received my PR rejection last week..
I am a University degree holder, and my school is actually one of the accredited schools here in Singapore...
Though I think the weak part of my application is that:
a.) I am handling S Pass
b.) I applied my PR on my 9th month stay in my current job, meaning my 9th month stay in Singapore as well...
Question, On my letter I am not sure if it is a general explanation that ICA made careful consideration on my application looking at the changes of residential period (what does this mean???) during the whole 9 months I did not leave SG, another factor is financial stability (I think it is about my salary, since I'm handling S Pass my basic salary is $1.8 but my job entitles me with commission) and lastly is CONDUCT (this I cannot understand...so far, I don't think I did anything wrong with regard to my stay here...did not do any exit just to extend my stay, no rejections with my EPEC prior, no rejections with my first S Pass application, I'm actually looking at staying here for long time since I started investing thru AIA, joined clubs/social organizations -> onePA, NTUC Club, etc.)
So that's why I have a big question in mind why?

?
I hope someone can enlighten me with some facts that would help me out....
