meet up, volley ball in Barcelona

I found this volley ball group on meet up app. I went there last suday and it was the first time to play volleyball.
The join fee was 8 eurso and it was worth it.
The coach trained me well. At first, I couldn't pass the ball over the net, but after coaching, I got better and better.
And we played games together, but I was lost because I didn't know the rules of the game.
All the training was conducted in Spanish, so I didn't understand most of it.
I should study Spanish harder.
