Question 104: Many questions

Q6: During my last enrollment in a WTF dojang (2003 to 2005), we were asked to pay for Belt testing fees, separately from the monthly tuition. Is this common?

Most every martial art class, club, or school will have testing fees in addition to tuition fees. The question should be how much is the testing fee. Some schools and organizations use the natural quest for rank and recognition as way to rip-off students by charging outrageous testing fees. You have to visit many schools to find one that best suits all your needs. Sometimes you just have to settle for a school that comes closest to suiting your needs. Independent classes taught in gyms, community centers, colleges, etc. usually have the least fees, but there are pro and cons to any choice. If a school owner is teaching full-time as a business, he or she has to make a reasonable profit. Some part-time instructors teach for free. Sometimes you get what you pay for, other times you do not.

Q7: Is the Sine-Wave theory a new science exclusive only to ITF Taekwondo or is it common in any other martial art?

The sine-wave theory is mostly unique to the ITF. I discuss the bogus science used in the theory in more detail in TKDTutor.com. The sine-wave movement is unnatural and a waste of time and energy.
