If you really want to learn how to play music this is the place to go. I must recommend that you come in with a open mind and allow the teacher to TEACH you. You will learn the foundations of the instrument and then everything will start to make sense.
If you come in and you want learn how to wank around and do crazy stuff instead of learning an instrument the traditional way, this is not your place. You are better of taking classes at Best Buy. Also make sure that you are prepared to commit to invest time in practicing at home.
Don't mess around, don't come to class unprepared, don't be disrespectful, or you will get kicked out.
You will come out an accomplished musician out of this studio if you apply yourself.
