I need advice, should I take this Marketing couse?

The main benefit from doing something like this is that you improve your "corporate speak". If you are gunning for big fish clients with traditional marketing departments (i.e. who went through the academic route) it might be helpful to understand from what perspective they are coming and how you can position yourself/your services within their experiences.

Definitely, if you're selling into big corps etc, you need to know the stuff. Nothing worse than sitting in a pitch having lingo fired at you that you don't understand.
