I passed level 1. It's almost useless unless you are in the banking or asset management industry. You can't list the "CFA" charter mark along with your name, eg. in name cards, unless you pass all 3 levels AND work in a relevant field. But once you obtain the charter, it goes to show you have a certain aptitude.

Of course you can list down in your resume that you have passed level 1 and level 2. Maybe it will help to a certain extent. For me, it didn't.
