Joe, what program are you taking that requires Hebrew? Fwiw, I was in a Hebrew day school until grade 7 and was fully fluent. I am very out of practice but last time I was in Israel for any extended period, I did regain my spoken fluency nearly all the way. Unfortunately I never did regain the ability to read without vowels
I also have adequate French and Spanish but am not by any stretch fluent, and the few times I have tried to converse with native speakers, they switched to English as soon as they heard my accent.
And I know a whopping three Maori words...
