Reddit reviews New Testament Greek for Beginners (2nd Edition)

I've used Mounce's and I do think it has good content, but I strongly dislike the sequence used. Also the exercises come straight from New Testament, which is also not helpful, because if you're like me once you've translated the first few words of the verse, there really is no secret as to what the rest of the verse is going to say. I personally prefer Machen's New Testament Greek for Beginners. The sequence is much better, in my opinion, and all of the exercises were composed by Machen. One downside is that Machen's may be somewhat difficult to go through without a teacher.

My university utilizes New Testament Greek for Beginners to teach Koine Greek. Perhaps working through it will be some help to you!
