First of all, you shouldn't pay for the trading courses as there is plenty of information online.
That is why I like forex, because all the knowledge you need is free of charge. There are so many different online sources, forums, videos, webinars, etc. that are available for everyone. However, not all of the people have enough discipline to makea personal learning plan and force themselves to learn on the daily basis. If you lack self-control and you still want to trade forex, you should find some courses and change your personality because forex requires a lot of responsibility, persistance and psychological stability.
If I were you, I wouldn't look for the courses but for the mentor. I believe that the knowledge and skills that you can acquire during a week course will be insufficient for successful trading and you are highly encounter lots of problems and questions after the courses are over. If you don't have the discipline to browse many forums in search for the answers, you'll definetely need a person who you can turn to in the time of need. He will guide you through the tough way of becoming a success. However, you should pay much attention to his trading experience and his indicators of success. You should ask him to show you his trading history where the amounts of successful and unsuccessful trades are depicted. He should trade for more than two years in order to give you advice. This criteria are the most important in choosing a mentor.
So, it is better for you to find a mentor rather than trading courses.
