Yes please do remember, you may not realistically have much of a choice (unless in London where I gather it is different).
We live in a smallish city and have a local catchment school, a city centre school with no real catchment but quite a lottery to get in (literally), and a village school with great rep but again, chancy, some years you will get in, others not.
Both the city school and the village would mean a bus ride from where we live, the village one with an added 20-min walk to the bus.
There are some other great schools in our city, but no point anyone where I live getting excited about them, as a) you won't get in on distance and b) you won't be able to get there without an obliging parent giving you a lift.
So what I am saying (long windedly) is by all means look at the options and see what is out there, thinking about the things mentioned on her and other MN threads, but beware of getting hung up on a wonderful school two bus rides and 7 miles away, as the chances ae it's a non starter.
Whatever you may read on MN, the vast majority of 11yos in England go to their local catchment state comp and do pretty well there.
