Re: how should i aproach my 4th kyu test?
Leading up to the test, focus on being relaxed and precise when doing your techniques. Otherwise, just do whatever your sensei suggests.
On the day of the test, take your time and try to relax. The biggest mistake people make in their testing is to tense up and rush their techniques. For a 4th kyu test, I doubt you will need to do any cardio work.
