Hi gooose, I'm not sure what's happening this year but last year, my application went in early July and it wasn't until September (after some prompting from me) that I finally got the call to come in for testing.
As a result of the delays, my o/s trip booked for late Dec (assuming the testing would be done) got in the way and I had to withdraw my application altogether. My own fault but I wasn't expecting such a long wait.
What I'm saying is, don't get too anxious. You might be in for a wait yet. Oh yeah, and don't go on a holiday before Jan 31 or you might be a member of the qf black list, just like me.
