I went like 2 years ago and I had such a good time it’s definitely worth going. It might be better to go with someone if that would make you feel more comfortable, but they split you up into rooms and groups anyway from the moment you start, based on which skill you choose. So there are always people who don’t know anyone else, and even if you did go with a friend you would be split up if you didn’t choose the same skill. It also teaches lots of really useful social and general skills that will help in sixth form. Only thing is it depends on the city you go to, as they are organised by different companies. I went to the one in Leeds which was really good, but I know people who went on the one in Harrogate and said it was ok but not great organisation. If you live in a uni city it will probs be fairly good.
