You can apply if you are a EU citizen.
They are 3 ways to enter:
EPL/S: need a
very good level of math physics (and english
)
EPL/U: You can apply with a theoretical ATPL
issued by the DGAC (very important they dont take CAA ATPL even "stamped" by the DGAC), and a 2 years after the baccalaureat (don’t know if they recognize A levels) degree. Good thing, you skip all the maths + physics ****, and the ranking is based on english marks!
EPL/P: same principle as EPL/U but with a CPL/IR (they provide you MCC and a few hours on Baron to get the "standard" IR level).
But first thing first, you must be fluent in french. And reading the type of questions you are asking here, you haven't read their website, have you?
