VSEPR is the Valence Shell Electron Pair Repulsion theory and it basically is a way to describe molecular shapes using rules of electron repulsion. Memorizing the rules will certainly help in drawing and naming the structures.
VSEPR stands for Valence-Shell Electron-Pair Repulsion. The VSEPR Model explains the experimentally observed shape of molecules and can predict distortions qualitatively but not quantitatively. It may be helpful to memorize the shapes and general angles, though you probably don't need to memorize exactly what VSEPR stands for.

VSEPR is an acronym for "valence-shell-electron-pair-repulsion" model. It explains experimentally the observed shape of molecules. Yes, we need to know it 100% as it encompasses all the various shapes that we will have to determine for each given molecule (tetrahedral, trigonal planar, etc.).
