Hi!

When do I know if Im an advanced singer and I could take the advanced lessons?

(Im using this amazing course for over a year and I sing realy well but i still get hoarse sometimes)

Hi Malki, I encourage you to try them and see how it goes! Each lesson series is a little different, so just because one feels too advanced, it doesn't mean the entire "advanced" page will be too advanced for you. 

If you haven't done the "level 2" beginner course, that could be a good thing to try next.
