Thank you all for the comments. She's doing the exam with her local dance school, whose students will all be wearing soft blocks. Her private teacher and also her associate program teacher say that it's better not to at this stage so she learns to use her feet better, which I totally understand. Problem is, my daughter will then feel uncomfortable if she's the only one in exam with flats! If she's not used to wearing them, will she then loose marks on her foot line?
