It is a great app better than other online class app. I have installed this oda class app for my littile brother , he is in 5th class. Now he is spending his major time in this app for his studies. It wiil help to understand any difficult topics in a easy manner. Exam orientated class are also available in this app. If we have any doubt about the studies, we can contact the teacher amd they will help you. They will provide modules of each chaperts. I will suggest this app for all the students whom studing in 1-10 classes.
