There is no such thing like "the best school" since each individual has different expectations and a lot of other factors come into play, like personal budget, time frame, motivation, goals etc. If possible one should go and visit the school/s of interest, make an appointment so someone will be available to show you around and answer your questions. That's an excellent way to get your own picture of the school and also a very good opportunity to meet and speak to some students and see what they say. And of course you should visit more than one school, to be able to compare.
