So you need to test to receive credit for how much you train? Your seeking acknowledgement via testing and rank? As egocentric as it sounds, rank is also about 'no-ego'. Perhaps your sensei(s) is just "testing" you. Try thinking of every class as a test.. You never know, maybe your sensei(s) will give you a field promotion.
Besides, what is rank? If your proficient with a technique, your uke will know it and others will notice it also.
