I am in the process of putting up translations for all the exercise sentences in Hansen and Quinn's Greek: An Intensive Course.
The translations may help some who are learning by themselves and need to compare their answers.
You can find the answers at http://atticgreek.wordpress.com/.
Let me know what you think.
The complete translations are up now.
I have also put a brief description of what each chapter of the book covers before the translations. That way you can see what grammatical functions are being worked on by the exercise sentences.
Needless to say, if you should spot any errors, I'd be grateful if you would send me a note -- either here or directly at the http://atticgreek.wordpress.com/ site. Many thanks.
