Thanks for your question. @baemax023 is correct. Currently, the only way to clear any existing progress in the School of Pipsology is to manually change the Track Progress selection from Yes to No This has to be done for every page that has Yes selected. It's definitely not ideal and a bit tedious. We've had that on our to-do list, to make clearing your progress easier. So thanks for your patience while we get that up and running.
