i took her vocal and guitar classes and ended both with marks above 90%. it is very easy to succeed in her classes as she is an amazing teacher and is very good at explaining. Don't be intimidated about trying the guitar class even if you've never played before, it is so educational. I saw kids who have never played before leave the class at the end of the semester able to play almost any song they want. I would highly recommend her classes she is so sweet and helpful, would not recommend going on your phone though.
