I'm a new MRT! I just received my MRT certification from the USRSA today! I went through all the testing down at the GSS Symposium a week ago in Orlando. I must say that Dave Bone (of the USRSA) and Bob Patterson were invaluable as they gave a "cram" session to the 7 of us who took the test. That was a pretty tough and stressful test as all of us were sweating it quit a bit. There's much more pressure to do everything right when you have people watching you and writing notes as you do it!!! My scores: Written - 92.3% Racquet Evaluation - 100% String removal/grommet replacement - 100% Handle sizing and gripping - 100% Stringing - 97.3% Whew!
