Ah, but changing the rules will change people's behavior, changing the statistics. We will have far more people failing out of STEM fields, with nothing to show for two years of study. Remember that a third of people who start in the sciences end up with a degree in the social sciences and humanities. Do you really want our CS courses to be filled with people who have no chance of succeeding in the major? People who cannot pass college algebra wasting the time of the class? Who does that benefit? The problem isn't statistics. The problem is not having an outlet for those drummed out of the sciences.
