Am I A Baritone Or A Tenor? Also, Could My Highest Note Increase With Time?

[Pkiss]

I am 15 and I sing G2 - G4, I am stuying in a musical school with singing degree and I have a proffesional opera singer as my teaher.

If you r have a good teacher why not ask them.

[bednobs]

I agree. Your professional teacher (who I presume you are paying) should answer these sorts of questions

[Pkiss]

She does not want to tell me, I don't know why.

[JimF]

Maybe she doesn't want to hurt your feelings.

[woofgang]

Ask her why she doesn't want to tell you.

You can extend range with practice.

[The Builder]

You probably know that G4 puts you halfway between the baritone (A4) range and the tenor (F4) upper range.

A lot of baritones can double as tenors in some pieces.
Voices tend to lower with age, but since you're learning, I'm sure OG is right saying that raising your range can be done with practice, at this early stage.

At 15 you probably have not yet reached full maturity. Your teacher may be unwilling to classify your voice as it may be different by the time your body has completed it's development.
In the meantime I would say try not to push your range at either end and safeguard your vocal chords until that development is complete.
What country do you live in?

I am in a musical school, classical singing is my degree, I passed an exam to get in, but she just really wouldn't tell me, she always hadges when it comes to that question, it's been too early to tell...I often don't believe in her teaching methods, because for so much years I have't improved, I still strain on higher notes and it gets worse with every new day and instead of increasing the vocal range, it actually gets lower...

I am in Bulgaria, but my teacher is russian so sometimes I barely understand what's she saying
