These days everyone is measured by how many pieces of paper we have, and less by what we can do. Even if you become self employed, you never know when it might go pear shaped and you need to go and work for the enemy...More paper=More options

But for the sake of a few pounds of earnings I would say do the course. Can you not work on saturdays to keep the earnings up?
