Calculus Vector transformations Tensors for GTR. To understand why we need these two theories. For that see the problems with Galilean transformation and equivalence of inertial and gravitational mass. The most important thing to study SR is to accept geometry as the concept behind it. The math is not difficult, it's the way of thinking you have to adopt. Draw space time diagrams, something to transform to another frame of reference (Lorentz transforms are available). Keep in mind that the view in the other reference frame is just a different view of the same situation that nothing really has changed, even if it looks different on Euclidean paper. It's merely a rotation, all lengths (t²-x²) stay the same. Learn to state problems in terms of events and the lines connecting them. You can't draw diagrams without translating the problems to space time coordinates properly. Special Relativity. SR really only requires some basic geometry and algebra. It's much more concept driven with the gedanken (thought experiments) than GR which requires some basic partial differential equations, basic differential geometry, tensor calculus and the field theory formulation of Newtonian mechanics (variation formulas).
