London Unis from Hertfordshire

Hello,
Im applying to unis soon and my first choices would be all London Unis (that's my main goal/priority) and I'm just wondering if anyone commutes from South Hertfordshire/North London to go to uni or if it is worth getting accommodation. I would be studying psychology at uni. Unis I am thinking of include
- UCL
- Kings College London
- Queen Mary
- Royal Holloway University
- University of Greenwich

Please let me know how the timetables work and if this is doable or not. I really am unsure and don't have anyone else to ask personally xxx

How long will it take. How do you attend travelling. If your arriving by train which station. Do you realise Royal Holloway is miles out of Central near Heathrow so might not be feasible by train whereas UCL is only a few minutes walk from Heathrow.

You need to do your research on the time you will need spending to each and decide then on when it is feasible. It would appear you would be better off staying but only you can decide that.
