are we supposed to know just the basic shapes such as

linear
trigonal planar/ bent
tetrahedral/trigonal pyramidal/ bent


or should we know all the shapes

trigonal bipyramidal/ seesaw/ t-shaped/ linear
octahedral/ square pyramidal/ square planar

I would know how to derive the basic shapes, but don't go crazy with this section, the MCAT dosen't cover too much on VSPER, but knowing a little more woudn't hurt.
