that is really bad! if i was u i would demand my money back as she hasnt shown u the key things you will be doing through out your career. most nail teks spend most of the time doing maintenance work than fresh sets and not show you how to infill a smile line is terrible.
thing is i was once in your shoes i did a BTEC beauty course and nails was apart of that, thankfully i was already trained in nails through EZ flow but it was terrible that i knew more than the teacher and was having to show my fellow students how to infill a smile line, i did say something but it wasnt like the course was a total waste as i got my beauty qualification out of it to.
