Hello everyone, This is Ashish. This is my second course on unacademy platform. I will teach chapter sound from 9th grade CBSE. This course is for everyone, specially for 9th class students and those who are preparing for engineering and medical exams. This is lesson number 1. In this lesson I have talked about chapter track, how we will proceed lesson by lesson, list of do's and don'ts during this whole course. I have added a new feature in this course "TMS" (The Marking System). In this course, I have added multiple activities in each lesson. I have also made a whole lesson only on examples and questions problems audience have to take a look at the question and pause the video according to their convenience and try to solve the problem. By trying they can gain the marks written in front of question and also they can know about their progress in this chapter lesson by lesson. In the middle of this lesson, I have little bit talked about sound and its inception as well.
