HS summer program for French?

i’m a current sophomore looking for a summer program for high schoolers where i can study (and gain credits for) french. i want to study either through a language immersion program (like middlebury or concordia) or a pre-college program (like studying french at a college/university), preferably a residential one. i know of a few, like the ones i’ve mentioned above, and i’m also interested in oxbridge’s l’academie de france. however, it’s pretty expensive, so i was wondering if there are any other similar programs?
