Gads..High school? I've been trying to learn it on my own. For some reason I have a unexplainable block. Guess I had better get a tutor. Are you available? LOL :)
I really would HATE to tell you just how long it's been, since I was in high school. LOL
Learning any language, after a certain age, is extremely difficult. Our brains are set up to learn any and all languages, easily, up to around 16. After that, it gets harder and harder and harder.
Have you tried records/tapes?
Did you take any languages in high school and college?
