I have guys ask me every year how the MN Preference Levels work, here is the description from the DNR website.
Preference levels
Each year that you apply for a license and don’t get drawn for one, you earn a preference point until you are drawn. If you are a first-year applicant or a previous-year winner, you are a preference level 1. The higher your preference level, the better chance of getting a license. For example, a preference level 2 has a better chance of getting a license than a preference level 1. Group preference works the same way. Some of our lottery drawings you can apply for as a group, such as this one; your group’s preference is the same as the preference of the member with the lowest preference level.
