Has anyone completed this course ? Do you do all the lessons. I mainly focus on audio lessons (1-4) and wants to move to level 2. Is it good idea to just run through the whole course or at least till level 1 and 2. I have this course quite some time now but not made much progress I am still stuck in Level 1 and keep doing it over and over again. For past few months especially I have increased my intensity. I am planning to complete this course by end of this year.
