what kills me is not knowing when we'll receive the invite. I thought it was based on BG completing (and which office sends it plays a big part as well of course) but looking at the trackers it's not really the case. I hate having to study and memorize all those names and numbers and then waiting and waiting for a test invite that could come in one, two, four, forever months so then I either study every day or re-start all over again. Maybe I should pause the studying till the tracker gets updated...
In the UK for instance, citizenship applicants can chose to take the test at any time during the application process, that would be a much better option in my opinion...
