Classes to break into Sales & Trading

Are there any good classes to break into Sales & Trading?

I want to learn more. I bought some of the books recommended by some of the other threads, but want to get some better insights. Foreign Exchange: A Practical Guide to the FX Markets by Tim Weithers wasn't too helpful. It just wastes pages but putting in pictures of money and listing out the currency codes and doesn't talk about how actual trading is done. Option Volatility & Pricing: Advanced Trading Strategies and Techniques was pretty dry and seems very dated. It's just hard to go through.

Has anyone here taken the Wall Street Prep Sales & Trading course? They have one in two weeks in NYC that I'm thinking about signing up for.

I know WSO has a review on their modelling courses for banking - but how are they for S&T? It's a lot of money but there isn't much out there that seems helpful. Taught by former S&T people and seems to be taught at major banks which i think is worth the money if that is the case.

Any other ideas on how to learn more to break in?
