It is something in-between. It explicitly anticipates that the reader will probably be studying GR, and includes sections on multidimensional manifolds, curved manifolds, parallel transport of vectors, covariant differentiation, Riemann tensor, Ricci-Einstein tensor, curvature scalar. One thing I like about the development is that it consistently carries the coordinate base vectors and base one form vectors (aka reciprocal basis vectors) throughout. As an engineer, this works well for me.
I've been writing up some notes on vector and tensor analysis, specifically customized to SR. If you are interested in receiving a copy, let me know via a private message. I will glad to email it to you.
