Great teaching material and I want to repeat it. How?
christopher_hathaway 2019-03-02 11:37 | Great teaching material and I want to repeat it. How? I would like to repeat the exercises in the chapters which I have done. Yes, I know I can do that just by clicking on the exercise itself, but how can I remove all the ticks, which show the exercise completed, so that I can again progress smoothly through each chapter just by pressing NEXT at the end of each exercise? |
