Is it useful to learn calligraphy?

I feel it's still useful. Your handwriting is good, others will take a high look at it, and entering the society will open some convenient doors for you in the future. You don't have to have a master's level. Now there are few traditional things in China, so you practice well. Nearby, you can still score a lot in your composition in the Chinese college entrance examination. That's what I do, hehe.
