This is a course in general relativity and the theory of the gravitational field. The student is expected to familiarise with the basic notion of general relativity and to be able to autonomously derive some of its classical results of astrophysical interest such as the precession of the perielio, the deflection of the light and the gravitational collapse of a sphere of dust.
