Cube presentation tomorrow

Our group of 6 of us will showcase our cube tomorrow. Simple it seems but I seriously question if such methods are really practical. I find that most of the time, the many things which we have to learn in our schooling life which includes up to tertiary and post-graduate level are simply theory. In the real world, majority of such knowledge gained is hardly used. What that is important is that of our survival, PR, EQ and other skills which will be vital. However, for the sake of passing the exams, such seemingly unnecessary things have to be done, like it or not.
