Hi everyone!

I volunteer with a lovely Spanish lady in her mid twenties.
I'm currently trying to assist her in her job search however she feels her English is letting her down.
I think it's quite good considering her almost non existent exposure to English (her partner, current job and our volunteering post involves little or no English despite the latter being in a school).
Does anyone know of any good resources that may improve her English?
