I use a combination of whiteboard software from BitPaper together with Zoom for voice and video. You don’t download Bitpaper but just follow a link I email to you. Yes, you do need to install Zoom if that is not already on your computer.
Like with my face-to-face tutorials we have an agreed day and time for our sessions and these last one hour or so. You log in a couple of minutes before the session starts and we are ready to go! Payment is made through online banking or suitable alternatives.
Notes from the tutoring session can be saved and sent to the student. The student can also upload material they want to cover, though this is not necessary – I have a large resource base to draw on.
