A proofreader looks for mistakes. You need an editor and even they can't determine whether or not a publisher is going to accept it. You could get a beta reader to read through for you. There are writing forums that give critiques, but you have to have a tough skin for criticism. Remember, not all those giving critiques have a clue on how to do it so you have to take those with a grain of salt.
I suppose it would be a good idea, to experiment and to get the proverbial juices flowing. Also to get feedback.
But i happen to think writing skills develop with writing!
I'd say this to you, just for fun.Depending on the kind of fiction you like to read: romance, horror, mystery...I'd say think of a couple of characters, put them in a confined space with a serious conflict. Make it 500 words and write it!
Oops! that's me! just jumped in here and didn't see this conversation. Roxann, i agree! no one can be taught to write and you certainly don't need a degree!
it might be useful for educational purposes in certain respects, but there are hugely popular novelists who never saw the inside of a university!
