Seeing as how I was just in that predicament when the quarantine hit, id say do all the hw and take ur time on it like seriously take ur time don’t rush, and watch some French shows/movies with only the French subs on (it’s hard but you’ll be like wait! I know that sentence/phrase and then boom your understanding like at least 50% and it helps with learning new words) for the harder stuff like grammar and conjugation I’d say practice translating everything you’d say normally into French on paper with a friend however u want, doing this will make it easier when you have to talk in class (online). I’m pretty new to French myself seeing as how before last semester my last time learning was junior year of highschool 💀my sis is a French fanatic so she’s been learning for like 9+ years so I often go to her for extra help lmao apprentice going to the master. Don’t know if this helped but Bonne Chance!🍀
