Hi Smoothsailing,
I am in the same situation as you - completed my online testing on 3rd Nov (for deadline 4th, same as yours I presume?). Still says "Online Testing Complete", still haven't heard anything back and I also felt the tests went reasonably well. I think there is quite a lot of variation in how long it takes ATC to get back to you. Some people in past years have reported taking up to two weeks, but I guess it could be even more.
I am also under the impression they might be doing things alphabetically. I put my original application in on 1st July and only got the email for online testing on 28th Oct - long after some others who submitted later. Since they are doing things in batches, I guess having a surname beginning with "W" doesn't' help. If you don't mind me asking, what letter does your surname start with?
Anyway all the best, suppose we just have to wait and see...
