My basic purpose of designing this blog is to get ride of students from private tution and academy culture.Secondly, sometimes you are present in the class physically but not mentally so as a result you can't give attention to your lecture, so you missed it. This blog will provide you video lectures with complete description. So you can take lecture any time and any where.
