@crazymama123 It is rather tricky. There are also other factors - to the ones that you mention I would add curriculum (e.g. which languages, sciences taught separately or not), co-ed vs single sex, scholarships and (access to) extra-curricular activities. Of course, some factors matter more than others but, at least in our case, it is being within certain parameters - e.g. on commute, being over 1 hour makes a difference, but not really if the difference is between 30 or 40 minutes.
We plan to sit down as a family and look at any offers together, assess pros and cons on all those dimensions and consider which matter most to us. And, of course, use any offers day to re-assess, including travelling to the school by public transport during a 'normal' day.
