From last year's bulletins, case numbers over 40,000 only became current in August and September. This does not give enough time for AOS (atleast from what I have read in the forums).
That leaves only CP. But the numbers are still called in order, so the only way that someone like me (case num AF60xxx) has a chance is if my country (Kenya) has fewer successes than the cap (7% or 3500), and there are lots of failures worldwide. What really surprises me is that over 60,000 slots are awarded to Africa alone!
From the pure fact that I have not been able to find a single success story with a high case number in this forum, I think it is very unlikely that I would get called. This is even more scary considering that there must be about 50,000 people with high case numbers worldwide EACH year!
If anyone of you have had an interview, or have had friends who have been lucky to be called for one, and have had high case numbers, it would be really motivating for people like me.
