I have only ten day so tell me some important chapters in PCM.

Physics Topic Wise analysis:

Though there is no pattern that AIEEE is following here but you can see that topics like Modern Physics, Optics, Heat and Thermodynamics, Electrostatics ,Magnetism & Magnetic Effects of Current ,EMI & AC Circuits and EM Waves have been scoring topics in decreasing order.

Chemistry

In average General organic chemistry + Functional Group I has most questions (avg=5.5) but AIEEE 2011 had only 2 questions from this topic, apart from thisCoordination Compunds,Atomic structure, Chemical Thermodynamics, Organic Chemistry Functional Group III, Chemical and IOnic Equilibrium,States of matter,Biomolecules, Chemical Bonding, Functional Group III are topics in decreasing importance according to the data.

Mathematics Topic wise analysis:

In MathematicsApplication of Derivatives, Indefinite Integrals, Definite Integrals & Area under the curve, Matrices and Determinants, Probability, Quadratic Equations, Inequalities, Progression are important topics in decreasing importance.
