I also welcome you David in your quest to learn Koine Greek. Another resource you might
want to take advantage of is a recent post of mine of actual beginner’s Koine Greek college
courses on YouTube. This could be a great supplement to your new books and it will give you
a familiarity to what you might expect if you take a seminary class in Greek some day.
Even if you only memorize the assigned vocabulary words, you will be ahead of the game and
will build a confidence in reading the New Testament in Greek as a bonus. I wish you success.

P.S. I have one more video to watch in the New Testament Greek 2 course before completing
it and can highly recommend it.
