Often regarded as the "gold standard" for HKDSE Core Mathematics and Science subjects, this calculator is a significant upgrade from the entry-level fx-3650P. However, many users only scratch the surface of what this powerful tool can do.
is an evolution of earlier Casio models, specifically designed to meet modern examination criteria while maintaining the "traditional" calculator form factor. Some enthusiasts at the HP Museum forum note that while it is vastly more capable than the original fx-50F—which only featured 29 programming steps—it represents a distinct branch from high-end "BASIC portables" like the FX-602P.
