Whats the best type of paints to buy?

I want to practice my painting skills for Art, I have to do a lot of paintings for my coursework and I'm not very good at using paint, so whats the best kind to use?

if your painting a house the best paint is wal paint. but if your painting a bike or something then buy spray paint! because spray paint doesen't chip like wall paint or hand paint does because its not as think!

Sorry I might of not made the question specific enough, Its got to be a paint that I can draw with for my Art lesson, lol I don't think my dad would let me paint the house x ]
