Is this a good singing range?

Is this a good singing range for a twenty year old girl?

• My range is from G3-B5 (almost C6). is this normal, I don't know, I never had a lesson, I don't know much about singing, just to sing through the Diagram (which I do). If you could check out this video for me, and tell me how I can get better, and if you could at least give me one POSITIVE thing about my voice, that be great.

• Answer:

  It is called "Diaphragm" not Diagram. Do you know where your diaphragm is located? It is the muscle you feel when doing crunches - if you pant...you'll fee the muscle moving. You use that for strength. Your range needs to be told in octaves. I have a 3 octave range - yours seems small by the way you described it. Maybe you should take lessons :) where's the video to check out?
