Hi. I think you should start by checking out the top schools in London schools-london.com/10-best-schools-in-london-rankings-and-fees/. There you will find only the top schools in London. Then you can find information about each school on the same website, and go deeper into the topic of schools and education in London in general.
I can advise you of a wonderful college in Oxford - Cherwell, where I studied, my sister, and now my eldest son, he applied there for full time courses. I really want him to be accepted there, because it is a really cool educational institution that gives a lot of knowledge and experience. Maybe other colleges are also good, but I don't know what the atmosphere and level of education there is like, because I have only this college behind me and it is decent.
Hi, I completely understand your concern about finding your child's right school in London. I don't have specific school recommendations, but I've found www.kidly.co.uk/ an excellent source for quality kids' clothing and items. Just thought I'd share that in case it might be helpful for you. Maybe you will find some stuff for school. Best of luck in finding the perfect school for your little one!
