I am writing books and now on the 12th different book and each of the previous I have rewritten each one 3-9 times when turned down by editors. My question is to ask where and what course can I take that teaches you how to write better. I have done all the homework sent out so far and yet still getting rejected with no explanation as to what is wrong. Jim
To answer your question on how to improve your writing craft...keep reading and keep writing. Read books in your genre with a critical eye and study the structures and key elements of bestselling and award-winning books in your genre.
