I did all the exercises. The only real mistakes I made were forgetting to use the psili at the beginning of the last word and not using the acute accent instead of the grave accent on every word with a word-final short accented vowel in Exercise 4. I also failed to notice that we're supposed to write the gender for each word in Exercise 2 until I started checking the answers, but then I just wrote them out and checked the rest of my answers.
My translations in Exercise 3 are also a little different from the answer key.
