So I started tutoring kids in the areas of Maths and Science following their own school's syllabus for a year now, and so far I've been gaining more and more student through connection of current students. Since I'm pretty OK on technology I use programs like Microsoft Excel to manage class times. The way I tutor those students is through Skype video calling where I would have a HD webcam so they can see my whiteboard in the background and a microphone so they can hear me properly instead of the built-in microphone on my laptop. It's a great way to reach to students, and even I don't charge students who are disadvantaged financially, and it's a fantastic experience. Does anyone have thoughts on this, online tutoring via video calling? If you do this sort of thing, do you use Skype or another service?
