Yeah, that almost sounds like an instructor who knows he shouldn't just test everyone (should have standards), but doesn't know what that should look like. So he picks someone without a good reason.Exactly. Personally I've never been bothered by rank but if I'm told I'm not testing I want To know why mainly so I know what to work on. Instructors should have no issue answering it and if they do then questions need to be asked.
It happened to me once I was told I couldn't test so I said "okay that's fine but can I ask why please" and the instructor looked surprised and stuttered and stammered a few things out then said he'd explain properly next time. When next time came after class he told me now I can test...funny that
