Hi all,
I'm just in High school but am very interested in the aspect of being in a sorority

Can anyone help me out w/pronunciation of letters, at least these?
Like when Phi is pronunced "fee" or "fie"
how "xi" is pronounced
how "chi" is pronounced
If there is a website which has various pronouncations, can you list it? THANKS! If there are any "exceptions" to the rules, please post them! THANKS!
