Tips: Take care of your folds at the beginning, and the rest should be fairly easy if you follow the tutorial exactly. Making careful folds, and making sure everything is properly aligned will allow you to get best results for the final product. This rule is something that should probably be kept in mind when making any origami model. Other than that, have fun!
Neat facts about this shape:
A bipyramid, as you can see, is a combination of two pyramids symmetrically placed base-to-base. It is also referred to as a hexahedron.
The wikipedia definiton of hexahedron is as follows:
A hexahedron (plural: hexahedra) is any polyhedron with six faces, although usually implies the cube as a regular hexahedron with all its faces square, and three squares around each vertex.
