Tricks to remembering orbitals

When I took Chem before, there was a trick involving the periodic table that could help you tell what orbital the valence electrons were in and what order to follow the orbitals for, but I can't remember it nor can I find it mentioned anywhere. Is there/what is the trick to remembering and figuring out the orbitals?

Another way to remember it is by the group the element is in.
Elements in group 1-2 are in ns orbital
Elements in groups 3-12 are in the (n-1)d orbital
Elements in groups 13-18 are in the np orbital.
n is the period number of the element.
