Re: Frustration about testing
Why ask sempai - I would have gone directly to your teacher.
The 60 hour minimums are guidlines designed as much to slow the over-enthusiastic as to ensure the accumulation of more skill and knowledge beyond what's being tested for specifically.
I would think with the amount of background you stated the minimum would be fine but if your teacher says no - perhaps its not.
No matter - the next time around set your sites on giving the best test that dojo has ever seen.
