When a St Andy's kid runs away from home because of exam stress, something has gone terribly wrong with the whole system. At one point St Andy's prided itself on being an equal-opportunity educator (save for the all-boys exclusivity). That was back when 'maximizing potential' meant that if a kid could reach a 'C', he would be coached to maximize himself to reach his 'C'; and an 'A' achiever would be maximized to reach his 'A'. Today, we've moved our goalposts so much that everyone's potential is expected to be an 'A*' within a certain narrow time-frame; failing which... let's just say our life-expectancy becomes significantly curtailed.
Of course, back then, some education was better than none. We grew up in much simpler times.
