Hiya, my friends mum is a dentist who often has nursing students. Best advice is to enjoy yourself, be as helpful as possible. Keep a notebook as youll probs find a lot of what you learn on placement is really helpful for lectures etc so its good to keep a record. In terms of working, its long days on your feet so comfy trainers or something is a gamechanger. Also a good lunch as those first few weeks will take some adjusting to energy wise 😅
