This course is intended for undergraduate students in Indian Universities with a background in Differential Calculus of Several Variables. Such a course was broadcasted in March 2016 under MOOC (NPTEL- IV) and that background will be enough to follow that course. It is kind of a threshold level compilation of lectures to Differential Geometry on which there is hardly any standard course at under graduate level in most universities.

There are few references listed with the template. However I wish to write the lectures notes myself to avoid vocabularies which usually companion such a course in Differential Geometry. I will upload my lecture notes (unfortunately hand written) after each module.
