The Irish Independent recently reported that there fewer students are taking Business at Leaving Cert level. I think this is a good trend. There are better things to study at 16 & 17 than Business. Why should a teenager be able "Draw and label a suitable 'organisation structure' diagram for a manufacturing organisation" (2005 Leaving Cert Exam) etc. Business Studies is not science. And, most of what they're teaching is pretty much meaningless until you've actually worked.
Learn Math, English, History, a language, Science, etc. If you have an interest in business do an MBA when you're 28.
