Does it sound like you? If you're going to get into an interview and they realise it sounds toss-all like you, it won't go down well. If it sounds like you but at the top of your game (or slightly beyond) then your teacher did an excellent job and why not? Generally, the posher the school the more help kids get with applications. Back in the day when we did them on paper, there were paid services too that effectively co-wrote them with kids, or ghost wrote them for the less articulate ones, going through through practice sessions writing them out by hand and reducing them to half size on a photocopier to check they were still legible (because that was what happened when they were sent off to the unis) and kept going until they had the closest-to-perfect copy you could get. That kind of thing is gone with the paper application process, but there is massive help available for those who can get it in the new process. If you don't take the advantage, you have to know that some other kid out there will be doing so, and be OK with that. They system isn't terrible, but anyone who thinks it runs 100% fair is kidding themselves.I've also written plenty of friends' CVs for jobs post-uni down the years, because I'm a professional editor and writer. I've never lied, but I've phrased things in a way that they might have been a bit shy of saying, while still aiming to sound as close to their voice as possible, just with more chutzpah. We often find it hard to sell ourselves but easier to see the best in someone we know.
