Does taking classes in creative writing help me to improve?

Creative writing is a natural process therefore, I doubt that classes would introduce anything new aside from brainstorming, research techniques and a few writing tips. So classes would help to improve just from a technical standpoint and not from creative writing since its down to your own thoughts you create.

No, creative writing is anything  to express rather than sharing information. Just need to create the mental space to write our stories. 

I agree with experts answers 

Thank you for invitation

Yes, of course. Unless you are exceptionally gifted, you need to take pertinent classes on Creative Writing so you would know how to develop your style and the technique.
