I think it would be very helpful, if the brilliant staff can group different techniques into different levels and, only level us when we have mastered those techniques in that particular level. This would help the brilliant's students to have a better grasp of the techniques, as they can be sure that they have learned the needed techniques corresponding to their current level. But those who play for points on brilliant, I know it won't be useful for you, but that defeats the whole purpose of creation of the Brilliant website. Right? I believe that this would really help us in being better acquainted with making better use of our knowledge and abilities to solve sums, and manage what we know about the subject and what we need to know.
