Letter(s: greek)

So... I got this letter in the mail today that reads:

Dear Prospective Member of Phi Theta Kappa,

Congratulations on your academic achievement!  As a result of your dedication to
scholarly success, the Phi Theta Kappa chapter at De Anza College extends to you an
invitation to accept membershp in the international honor society of the two-year college.  
Membership eligibility is based on your maintaining a cumulative GPA of at 
least 3.5, being currently enrolled at De Anza in at least three units, and your having 
completed a minimum of 18 letter-grade units; therefore, membership is a special
honor afforded to a small group of outstanding students.

... Eep. I'm a nerd!
