When you say your parents and family speak French, do you mean they speak to you in French, even if you reply in English? If that is the case, then, yes, I do think you could compact a year of French in the summer, but I would recommend that you enroll in a formal French class so you actually have outside accountability and don’t blow things off.
Otherwise, no. Don’t. You will likely end up with poor grades next year because you lack a solid foundation.
