im a completionest , so even thou I should be working on college grade math , I really just want to sit down and fully complete the world of math . the mastery set up is super fun , I get a ton of questions from different areas of math and I slam it out in 15 to 30 min , THEN I HAVE TO WAIT 7 MORE HOURS till I can do it again . now I can manually go in to a Group , for example we will say pre algebra , and I will have the videos and then the work tasks , well I don't want to wait time watching vids on things I all ready know ! I just want to focus on Completing the world of math quest ! ,so my question I s. can you set it up so we can just do mastery challenge back to back to back that allows us to just Slam out the Earth stages of Math , but as you get in to the college levels , I would be ok with it slowing down , so no one can just no life it in one session ! , so in a nut shell allow me to do the world of math in just mastery challenges , and remove the 7 h timer or reduce it to 30 Min . or have it biased on how often you use the web site
