When you get to Earl's Court (which will take about five minutes), get
off and take the next train to Edgware Road. It will probably be across
the platform, and you won't usually have to wait more than five minutes
(often, it's already waiting in the platform).

These trains are every 10 minutes, so you will have to wait more than
five minutes about half the time...

You will need a zone 1-6 ticket, which will be cheaper if you buy either
an Oyster card or a Travelcard.

A Travelcard isn't cheaper than a Z1-6 single (£6.70 vs £4.00).
