Prerequisites for beginers
Beginners are supposed to be familiar with fundamentals of Commutative Algebra, Topology and Differential Geometry. For instance, all this can be found in the following sources:

M. F. Atiyah, I. G. MacDonald, - Introduction to Commutative Algebra, - Westview Press, 1969. (Russian translation: Moscow, "Mir", 1972.)
Chapter 1: Rings and Ideals;
Chapter 2: Modules.
It is strongly suggested to solve exercises to these two chapters.

Maxim Kazarian, - Calculus on Manifolds - Moscow Independent University, MIM programme, Fall 2003.

John M. Lee, - Introduction to Smooth Manifolds, - Springer-Verlag, Graduate Texts in Mathematics, Vol. 218, 2003.
