This chart from Washington University in St. Louis is a great resource for additional help with molecular geometries, which is critical in assigning the correct point groups to molecules.

This flowchart from the Otterbein symmetry website includes every point group, including some very rare, very high symmetry examples such as I, O, and T_h.
