1. Each course is divided into 4 or 5 sections and each section has between 15 to 20 units. When you mark a unit as completed, it will have a blue tick on the right (see sample below).
  2. For units that are not marked as completed, the tick is light grey (see sample below).
  3. Each unit has a time indicator on the right (see images above). This is simply to provide you with an indication of how long it takes to complete the unit, you can complete the unit at your own pace.
  4. The blue and grey ticks are to enable you keep track of the units you have completed and those you are yet to complete.
