Intermolecule Forces and Physical Properties

I believe that this two subjects have been the hardest for me to understand by far I like how we did the chemical zoo by seeing examples and presentations done by other study but however; I was confused on VSEPR know what its purpose was and how its used left me puzzled. Intermolecular forces were a little bit better at understanding but still had confusing I learned that water is one of the stronger intermolecular forces.
