There are soo many people in Oct who have not been asked for CELPIP.
In fact i really suspect that because CELPIP's report format was a little unusal to indicate (report id + 3 spaces and pin) in the original EE form, some might have just put the report id there. At least that is what i did, until i looked at the Help link next to it while double checking.
I haven't been asked either, nor do i know many people who have been asked, so again the conclusion is that they only ask for it to a small number of people. So you got nothing to worry about. Good luck
