The Level 2 tracks may suggest these courses do build upon the Level 1 tracks like Sales Manager or Fianance Manager. That is not entirely trough. Several of the Level 2 tracks are designed to use some but not all of the courses from the Level 1 tracks. A good example is the BA00 - G2 ERP Business Analyst - track. This is a combination of several ADM courses and the REP01 track. The prerequisites of these tracks is the Fundamentals, not a Level 1 track.
