Choice of Master for third-year students: I am still hesitating between a dual degree and a non-selective master programme in Sciences Po. Can I apply to both and choose later?

If one of your choice is a dual degree, you must put it as your first choice and the non-selective programme as a second choice. You might be able to change later the rank of your choices, however please note that as dual degrees are highly selective, your application as to be a very motivated choice.
