I studied this on my own in high school. In college, talking with the advanced Greek teacher about some point, I picked up his Greek NT and began reading a passage. He stopped me, saying I was going too fast. Later I received permission to teach the book for one semester to some students. They came out of the class being able to use Greek better than the students who'd had three years (six semesters). They didn't know every parsing and declension, but they could follow the basic gist. So I recommend this to those who want a good introduction for general (Biblical) Greek usage. And it's also a good introduction for those who will go on to study Greek in more detail. Newer editions might be better. ( )
