In chemistry, chapters included in Physical Chemistry such as Thermodynamics, Equilibrium, Structure of Atom and others are completely formula based and 30% theory, so you should try doing numericals from it.

In Physics, focus on Ray Optics, Semiconductors, Kinematics and Current electricity as many questions are asked from these chapters.
