The POLYCET 2021 examination, with questions from Mathematics, Physics, and Chemistry, and a total time limit of 2 hours.
Mathematics Section (SECTION-I)
It covers topics like quadratic polynomials and their zeroes, linear equations, quadratic equations, degree of an equation, arithmetic progression (AP), coordinate geometry concepts such as centroid, parallelogram vertices, distance between points, and distance between tops of poles.
Other topics include: similarity of triangles, tangents to a circle, surface area of a cuboid, slant height of a cone, volume of a sphere, and trigonometry questions.
It also features questions on probability, statistics (median, mode, mean, central tendency), properties of numbers (HCF, LCM, composite number, irrational number), logarithms, sets, and polynomials.
Physics Section (SECTION-II)
Topics covered include laws of refraction and their components (incident ray, refracted ray, normal), focal plane, magnifying lens, image formation by a convex lens, and matching physical quantities with their SI units (Electric charge, Electric potential, Ampere, Coulomb, Volt).
It also contains questions on: heating elements (e.g., electric iron material), properties of lenses, resistivity and materials (insulators, conductors, semiconductors), Ohm's law and related concepts (potential difference, current, graph, units, conductivity), and units of lens power (Dioptre).
Human eye and vision defects (accommodation, presbyopia, myopia) are covered.
Magnetism topics include magnetic field lines, SI units of magnetic flux and magnetic flux density, electromagnetism's invention, and magnetic flux density definition.
Heat and thermodynamics questions include: final temperature of a mixture, definition of a calorie, identifying the body at a higher temperature, specific heat, and examples/non-examples of refraction.
Other topics include: refractive index and speed of light and angle of refraction when light passes from air to glass.
Chemistry Section (SECTION-III)
It covers atomic structure and quantum numbers (Principal, Azimuthal, Magnetic, Spin), Bohr's atomic model, and maximum electrons in p-orbital.
Electronic configuration and related principles (Aufbau, Pauli's exclusion) are included.
Periodic table topics: elements arranged by atomic number, Lanthanoids, elements in the 3rd period, and valency of a VA group element.
Chemical bonding: Ionic bond formation (transfer/electrostatic attraction), noble gas identification, formula formation, and triple bond composition.
Metallurgy: reactivity of gold, impurities in ore (gangue), corrosion (anode/cathode behavior), manganese minerals, and corrosion prevention methods.
Organic Chemistry: catenation, types of hydrocarbons (alkanes), melting point trend with molecular formula, carbon bond types, and functional groups (-CONH₂).
Acids, Bases, and Salts: litmus paper test for an acid, olfactory indicator property (odour), gas evolved
