@slickrick, no, you should not be “mastering” each lesson before moving on to the next. Spend at least 10 minutes (or as long as you want really) and move on to the next. I know it sounds counter intuitive, however spending too much time on a lesson may actually slows your progress. Move on to other lessons, skills courses, etc., and then come back to them after a while. Variety is the key. You will be amazed at the progress you have made without realizing it.
