There are many teachers and classes available here at WizIQ. Most give free classes, so try them out.
I have a full course that works primarily on spoken English. On Thursdays and Sundays two of them are available for free. To see what I am doing, go to

There is no "best" way. There is only what works for you. So shop around and find a good fit.
