Hello Aspirant,

See it is correct that Vector chapter consists of some portion of 3D geometry but only on the basis of Vector chapter you cannot solve all the 3D geometry questions because you should have basic knowledge of 3D figures as well and concepts used in basic 3D geometry are must to understand the concepts used in that of Vector portion so make sure to cover full 3D geometry.
