I'm currently working through the physics playlist and I've really enjoyed being able to answer questions in the practice questions, quizzes and unit tests. I've completed all the "mastery" content in 'one-dimensional motion', 'two dimensional motion' and 'forces&newtons Laws of motion' but moving onto further units there is no longer access to the practice questions and such.
I've tried looking into it and found people talking about a mastery reset timer or something like that of 15 hours. It has definitely been longer than that and still no more mastery challenges. Perhaps I'm missing something here but is there any way for me to continue my physics units with mastery practice questions along the way?
