Yes, it was related to adaptability points. Without them, I was getting less than 67.
Yes, seems like the wording has been changed to award 5 points to people like ourselves. But their logic is incomprehensible to me. My understanding (and in fact, my school lawyer's, too) when I applied was that these points were specifically intended for people like us, who have lived in this country for 2 years and adapted to the culture, way of doing things etc. It served its purpose when students who have been in Canada for 1--2 years could apply through the stream that subsequently got eliminated in June 2010. Now it looks like the system is out of tune---the stream was resurrected for highly-skilled applicants but it's not operating the way it used to. Some people get through, some get rejected, yet others (andy.fan) get rejected twice.
Again, I don't understand why when you get rejected in Sydney you can appeal, while the Ottawa officers have the final say on your application. I'm paying my freaking money for the application, and I wanna at least have a (semi)reasonable customer service and feedback. And sure, it would be nice to have things fair and consistent, because right now it's a lottery unless your case is bullet-proof. But again, can somebody define "bullet-proof"?
Summarizing, I believe things may still go random as they used to unless the freshly-minted Ottawa visa officers get more training on this and other issues.
