CG PET study guide
CG PET · Work through your exam, one topic at a time.
CG PET (Chhattisgarh Pre-Engineering Test) is the state-level entrance examination used for admission to undergraduate engineering programmes - principally B.E./B.Tech - in participating institutions in Chhattisgarh. It is aimed at candidates who have completed or are completing Class 12 with Physics, Chemistry and Mathematics, and who want to compete for seats through a state route rather than a national one. The test is multiple choice and is organised around three school-level subjects: Physics (roughly 30% of the paper), Chemistry (roughly 30%) and Mathematics (roughly 40%). Questions are pitched at the Class 11–12 syllabus, so the exam rewards thorough NCERT-level coverage rather than exotic problem-solving. Topics on this exam: Physics, Chemistry, and Mathematics. The CG PET study guide has 3 sections and about 955 words.
01Physics: Mechanics and Current Electricity
Physics in CG PET checks the Class 11–12 core: vectors, Newton’s laws, work–energy, rotational motion, SHM, electrostatics, DC circuits, optics and modern physics. Most questions are direct formula applications, but marks are lost through sign conventions, unit conversions and mixing scalar/vector quantities. Resolve vectors before applying ΣF = ma; equilibrium needs both ΣF = 0 and Στ = 0. Projectile motion: horizontal velocity stays constant; vertical acceleration is g.

CG PET Chemistry tests Class 11–12 physical, inorganic and organic chemistry: mole concept, atomic structure and bonding, thermodynamics, equilibrium, electrochemistry, kinetics, p-block elements, hydrocarbons, biomolecules and polymers. Numericals are mostly mole- or equilibrium-based; theory questions target trends and exceptions. Mole: n = mass/molar mass = particles/6.022×10²³. One mole of an ideal gas occupies 22.4 L at STP (0 °C, 1 atm).

CG PET Mathematics tests Class 11–12 algebra, trigonometry, coordinate geometry, calculus, vectors/3D geometry and probability. The paper rewards recognising standard forms quickly and checking domain restrictions before simplifying. d/dx(x^n) = nx^(n−1); use chain, product and quotient rules. d/dx(sin x)=cos x, d/dx(cos x)=−sin x, d/dx(e^x)=e^x, d/dx(ln x)=1/x.
