I think this is not an appropriate ratio because students need more exposure to the practical tools to succeed in the industry. Practical knowledge allows you to gain the specific techniques that become the tools of your trade.

Where theory is often taught in the ideal of a vacuum, the practical is learned through the reality of life. There are some things you can only learn through doing and experiencing.
