Flipping into falsetto

Mevs

Hi everyone
I have been practising for such a short time like a month so considering that I am an absolute beginner I find it really interesting that some people complain about flipping into falsetto when they go higher E4 above etc..
But the funny thing is I am hitting some notes above C5 but I just don't flip into falsetto I don't know why, am I having another passagio? lol,so does anyone have it and do you know why that happens? Or is it because I am not untrained?

Its difficult to tell without hearing you, some people think they are in chest when they are in fact in head, some people only have a certain initial range to work with from which to grow their voice. Everyone is different and has different passagios and abilities.
