Some of these web sites will have advertisers who are worth looking into also. And remember, if they offer free information, get it.
Attend all the free seminars you can, just be careful and don’t get pressured into anything you really don’t want or need. Most schools offer courses in finance and economics, but very few will have courses on the mechanics of the investment markets, if they do try taking the course. You may want to consider on-line courses, the New York Institute of Finance use to have such courses. Try to get some fee information from the stocks exchanges they all have (had) free booklets, SIAC and some of the regulators (FINRA SEC MSRB CBOE) may provide some free literature.
Good luck on your journey, study hard and you’ll be able to make it on Wall Street
