Overall I believe there should be a split in practical vs informational courses. The informational courses should have the majority percentage (either 60/40 or 70/30), however. The informational courses form a baseline knowledge of the field. If you only have the knowledge of practice, you can come to roadblocks that are more severe because of the lack of common informational knowledge of the field. For example, practical knowledge would be knowing how to build a burger. The informational knowledge would be knowing how to cook the patty.
