I just wanted to point out two helpful (and free!) online Biblical Greek resources.
Daily Dose of Greek
The first, is by one of my favorite professors at Southern Seminary, Dr. Rob Plummer. He has a vision to help people keep their Greek after seminary and part of accomplishing this vision is his excellent site, Daily Dose of Greek. Every weekday he walks through a verse explaining the syntax, vocabulary, and translation. On Saturdays he generally has a special topic or a guest host. The great thing about Daily Dose of Greek is that it is short (and helpful!) so it is easy to watch daily.
Another site that I recently was alerted to is Master Greek by Dr. Paul Hoskins. This site’s aim is to help with parsing. It is a simple web app that allows you to practice parsing Greek words. You can either do practice mode or quiz yourself. It works well in your browser on the computer or on your phone/tablet.
I was only recently introduced to this site/web app but it functions really well and I can see it being helpful for keeping up with my parsing.
