In the United Kingdom compulsory education ends at the age of sixteen. However, many students stay on and complete two more years. For some (and I include myself in this category) school just becomes a habit, something you don't want to give up as it is so familiar to you. School is your world and you know nothing else and so you just keep on going. Imagine my feelings when sixth form was over and there were no more classes to complete! Instead of feeling a sense of joy and relief I panicked — what was I to do? The logical and best option was to go to university and continue my studies there, so that is precisely what I did. Unfortunately, the end of secondary education in the U.K. is rot marked by any sense of celebration, like in other countries like the U.S.A. where students 'graduate' at the age of 18 and have a fancy ball. (In the U.K. you have to wait until you finish college or university before you can have that privilege). In the U.K. you just 'finish school!' The lucky ones have a respectable collection of qualifications to their name as souvenirs; the unlucky ones may have slipped through the net somehow and end up going back to education at a later date when they feel more like studying. Education is more than qualifications, I admit that. But they are what count at the end of the day. I made sure I got my fair share of them, just in case. Ask anyone what they remember most about school and they'd probably say the teachers. They are what makes education a humanistic experience and, therefore, are the most memorable: the good ones, the bad ones, the kindest ones, the most generous ones .. I was sad to leave them all, but l always was far too nostalgic! School dinners, of course, are remembered for all the wrong reasons — the long queues, the fat dinner ladies, the greasy food! Thank goodness, they have introduced healthy eating plans in schools! Pupils are luckier nowadays! Principally, school is all about belonging to a certain community and fitting in and making a contribution. I remember struggling at certain times in the year, trying to find time for musical productions and athletics competitions. I wanted to do everything and make my school proud. What was J more — an athlete or a musician? I was both, and a scholar too; an 'all-rounder', I suppose you could say. Luckily, I was able to rely on my natural ability to get me through the exams and didn't have to spend too much time studying. I just listened to my teachers and got through that way. I thank them, really I do. So, it will come as no surprise to you to find out that I became a teacher after l finished university. I couldn't get enough of school and so I stayed there! But this time it’s different. Now I can give something back to society. I face many challenges every day but I keep going.
