Yes, everything is exactly like you said, exept that fight lasts 1 minute, not 2. For example: we do all techniques, pushups and etc. with all karatekas that are grading to 5 kyu, then the same with 4, 3, 2 and then comes the time for 1 st kyu. - physical test, techniques and katas. After that goes kumite. There are no breaks between fights, just that time for changing between kumite partners. For example 1st kyu grading takes ~8 hours pure hard work. I'm in IKO2.
