1. Hello Ackbach and thank you for your welcome,

I teach maths for the IB DP programme and I was wondering if you have any resources you would recommend for online tutoring.

Mostly I am interested in your feedback on interactive, online whiteboards.

If I am sending this message at the wrong place or the wrong person, I apologize in advance!

Best regards,
Kostas Nassos
