I keep trying to post here, but it won't show up...maybe the fourth time will work.

The University of Texas has a free online "course" that is fairly basic:

I plan on having my DD14 use this online resource over the summer. She will take French 2 Honors in 9th grade, and she hasn't kept up with her French since she attended an immersion school from Pre-K through 2nd.

A tutor is a great idea too. Maybe an older kid at the new school can help? My eldest, DD16, is fluent and can help DD14. Also, her little sister, DD7, still attends the immersion school, and DD14 sometimes helps with her homework.
