IMHO if they're paying you to go to class, it makes it less focused on "do better at what you suck at" and more focused on "do better at what you are good at." Think of medieval times for a bit. In town, you would likely have one or two bakers, one good blacksmith, a cobbler or two, some weavers and seamstresses, lots of farm hands, and some town managers (I.E. lords or mayors or the like). These people don't usually take up their job because they had to (exceptions are the farmers and such which can be translated to the retail workers of today), they took up the job because they were good at it and people wanted what they had. Bakers don't bake because they were told to, they bake because they're good at it and people like bread. Blacksmiths don't make tools because they have no other skills, they make tools because that IS their skill. if this system didn't focus on what you do, but instead focused on what you get out of it (focusing on your improvement and contribution to the school instead of "grades"), it would be much better aimed toward people of all skill levels and types.
