Coursera has several paid and free online language courses developed by accredited universities. The quality of the courses varies, but the following recommendations have been well received — these courses are primarily for beginners who want an introduction to a new language.
École Polytechnique offers the only French course on Coursera; it’s technically for B1-B2 learners, although B2 learners may find it too easy.
If you are starting a language and enjoy structured courses with a (flexible) weekly schedule, Coursera is a great option — especially since Coursera offers financial aid for those who can’t afford to pay the course fees. Pair your studies with a tutor from italki or Verbling for speaking practice and you’ll be good to go!
