I need to learn about penny stock trading

My mentor for penny stocks called me last night and said things are starting to happen with the stocks he told me to buy a year ago. Well that doesn’t excite me too much because he has told me this several times and nothing has happened. I will give him a little more time and if there are no results I will take a penny stock trading course from a professional trader. Maybe I should have done that in the first place, but he is a friend and he gets so excited about his stock tips that I couldn’t say no. He hasn’t lost me any money, but he hasn’t made me any either.
