The days when teachers and students had to travel long distances to impart and gain some knowledge are all gone. Nowadays, there are all kinds of software and apps that allow teachers to carry out teaching and for students to learn and still be interactive. All that is needed is some wifi, an interactive whiteboard and the relevant software. Pencils, erasers, books, and even blackboards that need to be painted every year with pieces of chalk that are hazardous to health are not needed anymore.
