To make a schedule for your practice routine you need to determine what days you are going to practice. You then need to determine the length of time you will practice. I suggest you practice at least 20 - 30 minutes every day. Once you plan out your practice schedule, it is important to stick with it.
During the practice session itself, figure out what you are specifically going to practice. You should include a warm up, your scales, music that you need to work on, and something you enjoy playing for fun. By following a schedule you will begin to develop good practice habits that will enhance your knowledge of your instrument and your music.
