I left school as soon as I could weeks after my 16th birthday and walked straight into a job, now children must stay in education till they are 18 or doing an apprenticeship , I learnt on the job and probably learnt more that way and took my qualification later in life, I find most teachers are great with pupils who have an aptitude for their subject but hopeless with the ones who dont. The children who don't like maths are not suddenly going to love it between 16 & 18 , will they also have to take exams in the subject as this is the only way they can prove it is a success?
