One of the most important elements of our site is to offer resources to help people improve their game. We know how it is, you go, warm up and start playing and hope to improve by playing better players. In reality, that approach is hit/miss at best. It is through practice and drills that you develop the techniques that will help you raise your level of play and become more consistent.
Additional levels are on the To-do list and will be added once I feel like I have good content.
