Learn French with 18 year old Anja from Serbia. She arrived in Paris three years ago. She wants to study languages, tourism or journalism. Anja finds it difficult to get around Paris on the metro and she would like to know how to make things easier. To help her, we turned to Patrick Ung, who devised the Paris-ci la sortie du metro app (a pun on Par ici la sortie du métro – This way out) to help passengers pick the best routes when using the underground system. He has a lot of advice to give her.
