The first volume is "Mechanics" as in Theoretical Mechanics. It's a second or third year Physics course not a first year one. I took it third year, it was mostly fine. The treatment of Hamilton-Jacobi equation lacked motivation but it wasn't super difficult. I also took volume 2, "Classical Theory of Fields". That was much, much harder. Anything after that seemed unreachable.
