I must say I've had the complete opposite experience with ITTT.
They were courteous even though some of my questions were in line with Cheryl's - but I must say I did understand that selecting the $250 option to get the "complete" course (the $295 option) meant that I'd get more than a 10% discount. And I'm not a mathematics teacher...

I had great follow-through from my tutor, sound advice and very encouraging feedback even if I messed up.

Now I'm cutting my teeth in Czech Republic doing some volunteer teaching for two small village schools and a high school 5 days a week, but only a few hours a day using lots of games and quizzes. The kids love it, and I cannot understand why it took me so long to start teaching! I'm over 50 now and have finally found my calling! Thanks ITTT !
