My understanding of entering the Little Erasmus (fast stream) as opposed to the Lower Fourth was in order to gain a year which could later be utilised for the Oxbridge examinations in the Michaelmas Term after A Levels.
In my time I think there were 30-35 in the L.E. and I scraped in at around no. 34 or 35. In hindsight, I believe this was "a bad thing" and an average set of O Level (GCSE) results ultimately followed. Now, I'm sure if you are clever enough and work hard enough, it doesn't matter how old you are, but what it would have given me was added maturity and, just possibly, the realisation that these exams were important and worth working hard for.
Lastly, did the school really think it was going to have 30-35 Oxbridge candidates? I can't recall more than 10 or so ever getting in each year. So, were they hedging their bets at the expense of pupils who should really have gone at the normal pace?
So, L.E. - good or bad?
Not that I'm bitter you understand....
