I listened to JPA Utilization Part 1 first. It was definitely fun to listen to it because I first did the practical work and then listened to the theory, and realized, "Oh, that's what it meant! It works on this principle, so that's where it was used!" I didn't fully understand it after listening to it once, but if I listen to the utilization lecture again and keep getting used to it, it's a class that will fill me with confidence that I can use it well^^
