I hadn't realized how deeply the rot had set into the British education system until I read this report in the Telegraph.
Williams F1 is “frustrated” over the state of education in Britain today after the majority of school leavers applying for its apprenticeship scheme this year failed a basic maths test.
. . .
Of the 250 applications for its apprenticeship scheme this year, 45 were invited to an open day and 16 made it through to the tests round. Just six young people passed, with 10 failing to get more than half the answers right – a failure rate of two-thirds.
In previous years, the company allowed hundreds of applicants to sit maths tests early on in the recruitment rounds, but this led to such a high failure rate the company abandoned the tests until later in the hiring process.
There's more at the link, including the test questions (below the article). If you'd like to try them, you'll find the answers here. I tried several and had no problem getting them right, the majority of them using mental arithmetic alone!
If British students today can't handle such simple math problems, something's drastically wrong with their education system. Never having attended school in the USA, I can't say how US students would fare when faced with the same questions. Would any readers care to hazard a guess from their own experience?
