it took me 7 years and some change to get Cho Dan, I decided to go back to college in the middle after that 2 tears to Ee Dan 3 years to Sam Dan test, just tested last week My son was 6 years to Cho Dan, after that regular TSD waits he'll test for Sam Dan in Oct My daughter 3.5 years for Cho Dan and test for Ee Dan in Oct I guess my son and I are just slow learners, I think if you make all your tests 3.5 years is the quickest you can test for Cho Dan. My brother trains in TKD in Virginia and he said he will be testing for Cho Dan in about 2 years total training time Tang Soo mike
