PSC Geometry…
It looks like it is Public School Curriculum but I cannot find that spelled out anywhere.
That was my first thought, too.
maybe, but it’s only for geometry. the algebra classes, or any other class have it as a praenomen. however, that’s the best guess i’ve heard yet
A quick google search solved the problem:
Plane, Solid and Coordinate Geometry.
obliged, much.
De nada.
