It wasn't academic selection that failed me. It was the "not enough of it". I was at school at a a time when they were really trying to push those into the school who really may not have had the ability to go to uni - political correctness and all that was hailed high by those people who grew up in the 60s (i.e. the teachers). Most of the people in my year (I am talking about 50% of the year) dropped out before we got to the final three years of school, and then it was a whole damn lot better.
If you trace a lot of those bullying drop-outs now, you just know they should not have been at that school in the first place. Some of them really screwed up their lives, but they were given an opportunity, and threw it away... so there's a limit as to how sorry I could feel for them. Yes - that definitely convinced me that good academic selection + interviews is the way to go.
The Head has since changed at that school, they tightened up their selection criteria, switched a lot of the teachers, ... changed the whole way they teach even (!), and it went from a school that became undersubscribed when I left to an oversubscribed one with high-achieving pupils that even scare me (Year 7 kids winning prizes in Philosophy, when it's not even taught). The Head is largely responsible for turning it around, but it couldn't have been easy.
However, if they weren't selective, that turnaround would probably have never come.
