Drawing is all about interest and practice. Some people dedicate their lives to teaching others how to draw, paint and do other artistic things. You can however, not learn how to get your own style, because again, that only depends on shitloads of years spent refining your techniques. There is even specific schools that teach how to do stuff like this, so the question in my opinion is dumb.
It all depends on dedication and time, if you paint and try to improve on your own, you would reach a level of skill that would make them accept you, giving you a chance to radically improve.
There's tutorials how to draw on the internet, in many forms; as walls of text, simplified step by step pictures or videos on youtube and other video hosting sites.
It's possible to learn, if you are able to spend the necessary amount of time.
