My dad said if you become a tennis professional just make sure you get into the top hundred because you have to make a little bit of money. You make a living so you can pay your coaching and you know your travels.
ACT and SAT each have their own parts of the country. The GRE has its lock on graduate admissions. And so one could blame the companies but really economically they have no incentive to change things very much because they're getting the business.
