You know I have come to find out that it isn't the complications if the subjects alone that makes students fail, sometimes they need people like Sir pandey to pass difficult courses. It is supposed that simple terms should be applied to students to understand difficult subjects in class. Another thing is that not every teacher can actually deliver because there are some that really understand what students need and how they need it and there some that knows book very well and have the knowledge but aren't having the sound criteria about how to be a teacher or how to teach what they know..
