There are strengths and weaknesses to different mode of teaching. Online teaching do have an edge over other modes of teaching in certain aspects. 1. Online teaching can be more lively with the assistance of technology. 2. The students can learn at the pace that suits them. The smarter students don't feel bored for slow delivery of lessons and the slower students don’t feel left behind because the teaching is too fast. Often times this is the issue that produce feelings of frustration and lead to losing interest in studies. 3. The students can listen to lecture and do exercises over and over. Its a convenient tool for revision.

However there is a lack of interaction between teachers and students in online teaching. Most of the online teaching website these days offer lectures. Those come with exercises only provide answers. In Mathking, every question comes with a video explained solution. This makes it stand out from other teaching websites. To a large extent this answer a major weakness of online teaching, i.e, when the student can’t do a question, there is no one to ask. I gladly recommend mathking.my.
