A live tutor must possess basic computer skills at the very least. Online tutors also need to have access to several pieces of technological equipment. A computer with high-speed internet connection is mandatory, since all the lessons are imparted via the Internet. Also, a microphone and headset are essential technology gear, since online tutoring programs utilize voice technology. In addition, using a pen-tablet allows an online tutor to write on a whiteboard, while dealing with complex problems. Skype technology can be used to improve the live interaction potential.
