Guys please help in these two three things for Tef exam , I struggled to find from a long time.

1. A useful podcast with subtitles in French. I am using RFI and radio canada but it has no subtitles. 2nd similar mock tests other than prep my future. Which has quantity in reasonable price. I use TefCanada .ca but it is not reliable. Either too easy or either too difficult. 3rd is there any way to turn the virtual keyboard into French while keeping the physical keyboard in English.

Please tell if anybody knows.
