I talked to her before i decide that she is right for me. Trial lessons serve that purpose.
Also, don't sign up for too many classes. It's always useful to gain exposure to different teaching styles and approaches, so perhaps you should commit to her for twenty lesson, and then supplement that with another ten lessons with someone else, just to vary things up.
Most importantly, don't forget to supplement your lessons with additional materials and exercises, which can be done in your own time. You may gain a lot of knowledge and insight during the classes, but most growth and development is achieved outside class time.
