The moment of inertia of a rod about an axis through one end is 1/3 ML^2. The moment of inertia about an axis through the center of mass is 1/12 ML^2. The moment of inertia about an axis parallel to the axis through the center of mass and a distance d from it is 1/12 ML^2 + Md^2. So, the moment of inertia of a rod of length L and mass M being rotated about a point located 0.300 L from one end is 1/12 ML^2 + M(0.300 L)^2 = 0.123 ML^2.
