Spanish Speaking Classes

I thought there was already a thread regarding Spanish speaking classes but, looking through a bunch of threads, I didn't see it.

I went yesterday and spoke with an employee at the Ministerio de las Relaciones Exteriores about Ecuadorian naturalization.

I thought that one could get a waiver from the Spanish language interview if one was as old as I am (78 years old), but found out that the waiver does NOT include being able to opt out of an interview in Spanish.

I had heard that Spanish "fluency" means being able to speak Spanish at the high school level. 

1)  Does anyone know if this is true regarding completing a Spanish fluency interview for Ecuadorian naturalization.

I took two years (four semesters) of university Spanish, making "A's" and I can speak Spanish well enough to get my needs met.  However, I have impaired hearing and wear bilateral hearing aids.  So, conversational Spanish is much more difficult for me than merely speaking what I need.  Many times, I don't even understand English (my primary language) without asking for what is said to be repeated! 

2)  Does anyone have recommendations for effective Spanish classes or Spanish speaking groups such that I can reach fluency at the high school level?

Thanks for any and all help. . . .
