Catalyst JEE Prep XII

Build your next skill.

A focused JEE problem-solving course for Class 12. It covers nine high-yield chapters, three each from Physics, Chemistry and Mathematics. Every topic has two pages of JEE-style worked problems (multi-concept set-ups, shortcuts and the traps that exam options are built on) and a ten-question timed drill with answers and worked reviews. What you will cover: • Physics: electric charges and fields (Coulomb superposition, dipoles, Gauss's law for lines, sheets and spheres), current electricity (resistivity, networks, real cells, maximum power, Kirchhoff's laws, bridges), and moving charges and magnetism (circular and helical paths, velocity selectors, Biot–Savart and Ampere results, forces and torque on currents) • Chemistry: solutions (concentration scales, Henry's law, Raoult's law, colligative properties and the van't Hoff factor), electrochemistry (Nernst equation, ΔG° and K, Faraday's laws, conductance and Kohlrausch's law) and chemical kinetics (rate laws, half-lives, Arrhenius equation, mechanisms) • Mathematics: matrices (products, special types, inverses, linear systems), determinants (properties, Cramer's rule, areas) and application of derivatives (tangents, rates, monotonicity, maxima and minima) This course does not cover the full Class 12 syllabus: optics, modern physics, organic and inorganic chemistry, integration, vectors, 3D geometry and probability are not included. For complete chapter-by-chapter coverage, pair it with Forge XII. Two sections (the potentiometer, and tangents and normals) carry a short note because they have left the current CBSE syllabus. Always check the official notice for your exam year. Practise as you go: each lesson ends with quick checks, and each of the 9 chapters has a practice test that draws 10 fresh questions per attempt from a 20-question tagged bank, with unlimited retakes. Expect roughly 15 hours of self-paced study.

Take away something useful.

• Add Coulomb forces and fields as vectors and find null points
• Use dipole formulas and Gauss's law for lines, sheets and spheres
• Solve networks with real cells, Kirchhoff's laws and bridges
• Find radii, periods and pitches of charges in magnetic fields
• Combine Biot–Savart results and find forces and torques on currents
• Convert between concentration scales and apply Raoult's law
• Use colligative properties with the van't Hoff factor
• Apply the Nernst equation, Faraday's laws and Kohlrausch's law
• Use rate laws, half-lives and the Arrhenius equation
• Work with inverses, determinants, Cramer's rule and derivative tests

Everything you get.
