Do we need know the notation for vsepr (AXE)?

Technically no you would just need to memorize the shapes and when each geometrical figure should be applied. I will admit though that the formula will definitely help.

Not exactly - you could memorize each individual shape based on the number of bonded and unbonded pairs. However, you are basically doing the same with the AXE notation and it's extremely helpful to know. You can memorize which AXE formula corresponds to a certain shape, which will make it easier to remember.

The AXE formula can be very helpful when doing problems since each AXE formula in VSEPR is unique. For example, you can draw an AX3 molecule and know that it's trigonal planar which would make the problem much easier. In general though, you don't need to know each one, but it can be very helpful on tests and for future problems in bonding.
