For IÉSEG’s English‑taught MSc programs in general, tuition is usually in the €18,800–€25,800 range for the whole program, and it can be lower if you grab one of their early‑bird or merit scholarships (so applying early really helps). You should plan roughly €1000 – €1,300 per month to live in Lille (rent, food, transport, basics) and more for Paris, maybe up to €1500 – €2000. You won’t die without French as the program is in English and there are lots of international students. You can find internships/jobs in English‑friendly companies but you’ll need to put in extra effort and at least basic French to really open up the local job market too.
