I am going to give you an easy understanding approach to the subject. Alongwith solution of all the doubts and notes. I strictly deny that some subjects require rot learning at any point. Students need to und erstand the concept behind every topic and understand its practical impact on life and every subject becomes easy. I'm a beginner at teaching but i know how i would prefer to be taught. This is the reason i'm trying to be a friend to students and help them conquer the battle. + more - less
