This is exactly what I have been counting on.
Thanks very much you wonderful people.
I currently have 65 points, so even if CO discounts degree I'm still left with 60 passing mark. This being "grey area", I'm just hoping CO will not outright refuse visa and instead settle with my assessed diploma.
After the introduction of invitation system, I've seen so many getting refused in spite of having passing mark. Jumping the queue by overclaiming points appears to be summarily rejected.
