First of all, read the course descriptions carefully. Those should give you quite a good starting point. You can also use our Lindy Roadmap or the Level up map to better evaluate which level would be the most suitable for you.
If you have not danced (swing dances) ever before, our beginners' courses would be for you. Unless explicitly mentioned otherwise, in the beginners' courses we start from zero and no previous experience is needed.
Usually, the higher levels are meant to be taken multiple times before proceeding to the next level. Recommended minimum level durations are listed in the Lindy Roadmap, but we also often mention recommended duration and minimum requirements in the course descriptions.
