Also, I'm not sure what hellish grading system you're used to where "A" means "1% elite". In most contexts, it means "competent": A student at most educational institutions in the US can expect an A if they grasped the class material and didn't flub the tests and assignments.
There are places where consistent, well intentioned sub-competence is sufficient, a high-availability, technically complicated, ultra high volume paid service running on retail margins is not one of them.
