I have been singing for many years but just on my own without having any lessons. should I go for beginners or advanced then?

which one should l take

i would say try one lesson out of each and then see which one u feel more comfortable with but i am the same as you so i would pick beginner .

Good advice, Kenzie! 

I recommend the beginner course to fill in any gaps with your technique, going from self-study to having a vocal coach. I promise, you'll still be challenged!
