You can, if you wish, purchase the Course Materials only for any module, but if you did this DP Music Services would not mark and monitor your work at the end of the module. This would speed things up a little, but would not address any weaknesses in your work or general comprehension of the current module. If you feel confident regarding your grasp of work thus far, there may be few problems (if any) caused by such a decision, but it is not recommended for large sections of the course unless you are not too concerned about your results at Grade 5 level.
