Why bother to resist a rank if the testing is that simple (that he could sneak it in on you)? I'm genuinely curious why you wouldn't accept a rank you were clearly (by your instructor's actions) ready for and could attain that easily.Yeah I was a brown belt for about 20 years simply because I didn't care about testing and I'd still be a brown belt today but my instructor at the time did a in class test for me without me knowing what it was and then promoted me. If he'd asked me to turn up on specific date to test I'd have said no the only reason I ever wanted new belts was so I could learn new material
