ATIT Syllabus

ATIT 2026 syllabus

The ATIT technical syllabus was based broadly on Class 11 and Class 12 study. The sections below organise the preparation scope in a student-friendly way. They do not replace the official syllabus or sample-paper instructions. Students needed both conceptual understanding and objective-question practice.

Mathematics syllabus and priorities

Sets, relations and functions: Students should understand set notation, union, intersection, complement, Cartesian products, relations, domain, range, different types of functions, composition and inverse functions. Questions may test whether a relation is reflexive, symmetric or transitive, or ask for the domain of an algebraic or trigonometric expression.

Complex numbers and quadratic equations: Preparation should cover the imaginary unit, algebra of complex numbers, conjugate, modulus, argument, Argand-plane representation, polar form, roots and the relation between roots and coefficients. Quadratic inequalities and the nature of roots are important for quick MCQs.

Matrices and determinants: Candidates should practise matrix types, operations, transpose, determinant properties, minors, cofactors, adjoint, inverse and solving linear equations. Determinant simplification through row or column operations saves time. Students must recognise when an inverse does not exist.

Permutations, combinations and probability: Topics include the fundamental counting principle, arrangements with and without repetition, circular arrangements, selections, conditional probability, independent events, Bayes’ theorem and basic random-variable ideas at the senior-secondary level. The main challenge is deciding whether order matters.

Binomial theorem and sequences: Candidates should know general and middle terms, coefficients, arithmetic progression, geometric progression, sums and standard relationships among means. Objective questions often require identifying a specific coefficient or using symmetry instead of expanding fully.

Trigonometry: Study trigonometric ratios, identities, equations, inverse trigonometric functions, properties of triangles, heights and distances. Exact standard-angle values and transformations are essential. Students should avoid relying only on a calculator-style approach because the test checks symbolic reasoning.

Coordinate geometry: Lines, slopes, distance, section formula, pair of lines, circles, parabola, ellipse and hyperbola form a major area. Candidates should connect standard equations with geometric properties such as focus, directrix, eccentricity and tangent. A small sketch can prevent sign mistakes.

Limits, continuity and differentiability: Preparation includes standard limits, algebra of limits, continuity, derivative from first principles, derivatives of standard functions, implicit and logarithmic differentiation. Candidates must understand where a function or derivative is undefined.

Applications of derivatives: Increasing and decreasing functions, tangents, normals, rates of change, maxima and minima are central. Students should distinguish a stationary point from a confirmed maximum or minimum and check endpoints when required.

Integral calculus: Cover indefinite integrals, standard forms, substitution, partial fractions, integration by parts, definite-integral properties and area under curves. Formula memory must be supported by practice choosing the correct method.

Differential equations: Students should study order, degree, general and particular solutions, variable separable equations and basic first-order linear forms included in Class 12. They should verify a solution by differentiation when options are close.

Vectors and three-dimensional geometry: Important ideas include vector addition, scalar and vector products, direction cosines, equations of lines and planes, angles and distances. Drawing the direction or plane normal helps interpret formulas correctly.

Statistics and mathematical reasoning: Mean, variance, standard deviation and interpretation of grouped data may appear. Mathematical reasoning includes statements, connectives, implication, converse and contradiction. These questions can be scoring when definitions are clear.

Mathematics carried the highest number of questions, so it deserved regular daily practice. A useful method was to maintain a formula notebook, solve mixed chapter sets, mark recurring errors and redo them without seeing the solution.

Physics syllabus and priorities

Units, dimensions and measurement: Students should know SI units, dimensional analysis, significant figures, error propagation and basic measuring instruments. Dimensional checking can eliminate impossible options quickly, but it cannot determine dimensionless constants.

Kinematics: Topics include one- and two-dimensional motion, graphs, relative motion, projectile motion and uniform circular motion. Candidates should interpret displacement-time and velocity-time graphs instead of learning equations without context.

Laws of motion and friction: Newton’s laws, free-body diagrams, equilibrium, connected bodies, pulleys, friction on horizontal and inclined surfaces and circular dynamics need practice. Most errors come from missing a force or choosing the wrong direction.

Work, energy and power: Cover work by constant and variable forces, kinetic energy, potential energy, conservation of mechanical energy, collisions and power. Students should identify whether external work or non-conservative forces prevent simple conservation.

System of particles and rotational motion: Centre of mass, momentum, torque, angular momentum, moment of inertia, rolling and rotational energy are important. Comparison questions become easier when students know standard moments of inertia and the parallel/perpendicular-axis theorems.

Gravitation: Universal gravitation, acceleration due to gravity, potential, orbital velocity, escape speed and satellites should be prepared. The signs of potential and energy require care.

Properties of bulk matter: Elasticity, viscosity, surface tension, fluid pressure, Bernoulli’s principle and thermal properties are included in senior-secondary mechanics and matter. Units and limiting cases often reveal the correct answer.

Thermodynamics and kinetic theory: Students should understand temperature scales, heat transfer, calorimetry, gas laws, the first law, thermodynamic processes, heat engines and molecular interpretation of gases. Sign conventions must be kept consistent.

Oscillations and waves: Simple harmonic motion, spring and pendulum systems, wave equation, sound, standing waves, beats and Doppler effect are central. Phase relationships and boundary conditions matter.

Electrostatics: Coulomb’s law, electric field, Gauss’s law, potential, capacitance, dielectric effects and energy stored in capacitors require both conceptual and numerical practice. Symmetry is the key to Gauss-law applications.

Current electricity: Candidates should cover resistance, resistivity, series-parallel circuits, cells, Kirchhoff’s rules, Wheatstone bridge, metre bridge and potentiometer. Circuit redraws can simplify complex networks.

Magnetism and moving charges: Lorentz force, charged-particle motion, Biot–Savart law, Ampere’s law, magnetic dipoles and material properties are important. Students should use the correct right-hand rule rather than guess directions.

Electromagnetic induction and alternating current: Faraday’s and Lenz’s laws, inductance, AC quantities, reactance, impedance, resonance, transformers and power factor should be studied. The negative sign in induced emf expresses opposition to change.

Electromagnetic waves and optics: Review the spectrum, ray optics, mirrors, lenses, optical instruments, interference, diffraction and polarisation. Sign convention and diagram interpretation are frequent sources of error.

Dual nature, atoms, nuclei and semiconductors: Photoelectric effect, de Broglie relation, atomic models, radioactivity, nuclear energy, semiconductor devices and elementary digital electronics form the modern-physics block. These topics often yield direct formula or concept questions.

Physics preparation should combine short conceptual questions with timed numerical problems. After each mock, the student should label an error as conceptual, formula-based, unit-related, calculation-based or caused by time pressure. That classification shows what to fix.

Chemistry syllabus and priorities

Some basic concepts and atomic structure: Mole concept, stoichiometry, concentration terms, empirical and molecular formulae, quantum numbers, electronic configuration and atomic models are foundational. Students should practise balanced-equation calculations.

Periodicity and chemical bonding: Trends in size, ionisation enthalpy, electron gain, electronegativity, bond types, Lewis structures, VSEPR theory, hybridisation, molecular orbital ideas and intermolecular forces are essential. Understanding exceptions is more useful than memorising a single trend.

States of matter and solutions: Gas laws, kinetic theory, liquid properties, solution concentration, Raoult’s law, colligative properties and abnormal molar mass should be prepared. Unit consistency is critical.

Thermodynamics and equilibrium: Enthalpy, entropy, Gibbs energy, Hess’s law, chemical equilibrium, ionic equilibrium, pH, buffers, hydrolysis and solubility product require regular numerical practice. Students must distinguish equilibrium constants expressed in different forms.

Redox and electrochemistry: Oxidation number, balancing redox equations, conductance, electrochemical cells, Nernst equation and electrolysis are key. Cell notation should be read systematically.

Chemical kinetics and surface chemistry: Rate laws, order, molecularity, integrated equations, half-life, Arrhenius relation, adsorption, catalysis and colloids may appear. Graph-based questions test whether the student understands the equation rather than just remembers it.

Hydrogen, s-block, p-block, d- and f-block: Preparation should include trends, important compounds, oxidation states, anomalous behaviour and practical uses. Comparison tables help organise inorganic facts, but students should connect them to electronic configuration.

Coordination compounds and metallurgy: Nomenclature, ligands, coordination number, isomerism, bonding, colour, magnetic behaviour and extraction principles are important. Accurate IUPAC naming can provide quick marks.

Organic chemistry fundamentals: Electronic effects, resonance, hyperconjugation, acidity/basicity, intermediates, reaction types, isomerism and purification form the base for all later chapters. Students should learn why a reaction occurs, not only the final product.

Hydrocarbons and halo compounds: Alkanes, alkenes, alkynes, aromatic hydrocarbons, haloalkanes and haloarenes include preparation, reactions and mechanisms at Class 11–12 level. Markovnikov orientation, substitution/elimination competition and benzene reactions deserve attention.

Alcohols, phenols, ethers, aldehydes, ketones and acids: Candidates should compare reactivity, named reactions, oxidation/reduction and diagnostic tests. Conversions become manageable when reagents are grouped by purpose.

Amines, biomolecules, polymers and everyday chemistry: Basicity, diazonium chemistry, carbohydrates, proteins, nucleic acids, polymer classification and medicines/chemicals in daily life are frequently direct. NCERT-level statements are useful for revision.

Chemistry can improve total score because many questions are shorter than Mathematics problems. A daily blend of physical calculations, inorganic revision and organic reaction practice prevents one subdiscipline from being neglected.

English syllabus and skills

The English section broadly tests whether the candidate can understand written material and use standard grammar and vocabulary. Preparation should include reading comprehension, sentence correction, fill-in-the-blanks, vocabulary in context, synonyms, antonyms, one-word substitutions, idioms, para-jumbles and basic verbal usage.

For comprehension, students should read the passage before choosing an option and separate the writer’s statement from their own outside knowledge. For grammar, revise subject–verb agreement, tense, articles, prepositions, pronouns, modifiers, parallel construction and active/passive use. Vocabulary is best learned in sentences rather than isolated word lists.

The English section can be completed efficiently, but rushing creates avoidable mistakes. Words such as “except”, “not”, “least” and “incorrect” change the task. Candidates should underline or mentally flag them.

Logical Reasoning syllabus and skills

Logical Reasoning may include series, analogies, classifications, coding-decoding, directions, blood relations, arrangements, syllogisms, statement–conclusion questions, assumptions, data sufficiency, calendars, clocks and basic visual or numerical patterns.

The aim is not advanced mathematics. It is accurate rule identification. Students should write compact diagrams for seating, family and direction questions. For syllogisms, a simple Venn representation is safer than relying on everyday meaning. In data sufficiency, the task is to decide whether the information is enough, not necessarily to calculate the final value.

Reasoning speed improves through repeated exposure to question types. Candidates should not memorise an answer pattern; they should learn a method and test it against each condition.
