Would she have retained enough French to enter French 2? She could review over the summer if you think she’s up to it and if her GC would agree to sign her up for French 2.
Typically, when universities say “2 years”, they mean “through level 2”, so that if she reviewed her middle school French and perhaps some French grammar/vocabulary now, took French 2 senior year, and got a C in it, she’d meet the University admissions requirements. (And for admissions purpose all she’d need is “French 2” on her transcript and no F by graduation.)
