Mathematics Revision Strategy for CET Delhi Polytechnic 2026
Mathematics is the highest-weightage subject in CET Delhi Polytechnic, accounting for approximately 50% of all questions. Allocating Days 1 to 3 exclusively to Mathematics is the single most important decision you can make in the last week.
High-Priority Topics:
- Real Numbers: HCF, LCM, Euclid’s division lemma, proving irrationality of √2 and √3
- Polynomials: Finding zeros, relationship between zeros and coefficients for quadratic and cubic polynomials
- Pair of Linear Equations: Graphical method, substitution, elimination and cross-multiplication; consistent and inconsistent systems
- Quadratic Equations: Factorisation, quadratic formula, nature of roots using discriminant (b²−4ac)
- Arithmetic Progressions: nth term formula aₙ = a + (n−1)d; sum formula Sₙ = n/2(2a + (n−1)d) — direct formula-application questions
- Triangles: Similarity criteria (AA, SAS, SSS), Basic Proportionality Theorem, Pythagoras theorem and its converse
- Circles: Tangent properties, angle subtended by a chord at centre and circumference
- Coordinate Geometry: Distance formula, section formula, midpoint formula, area of a triangle using coordinates
- Trigonometry: Standard ratios and reciprocals, complementary angle identities, standard identities (sin²θ + cos²θ = 1 and derived forms), heights and distances
- Mensuration: Surface area and volume of sphere, hemisphere, cone, cylinder and combinations — high-marks questions
- Statistics: Mean by all three methods, median and mode from grouped frequency distribution — always tested and straightforward to score
- Probability: Classical definition, simple events and complementary events
Mathematics Revision Tips:
- Maintain a single A4 formula sheet covering all chapters and read it every morning before starting revision
- Write all Trigonometry identities from memory 3–4 times until you can reproduce them without looking
- Mensuration is calculation-heavy — practise rough-work speed and double-check unit conversions (cm to m) in every question
- Statistics is straightforward and scoring; solve at least 5 grouped-data problems before exam day
- After each MCQ practice set, identify which chapters gave the most errors and prioritise those the next morning
Physics Revision Strategy for CET Delhi Polytechnic 2026
CET Delhi Polytechnic Physics tests the application of laws and formulas — not derivations. Focus on memorising equations, understanding direction rules and practising numericals so you can solve Physics questions quickly within the 60-second pace the exam demands.
High-Priority Topics:
- Light — Reflection and Refraction: Mirror formula (1/v + 1/u = 1/f), lens formula (1/v − 1/u = 1/f), magnification, sign convention, ray diagrams for all six standard cases
- Electricity: Ohm’s law (V = IR), series and parallel resistance, power formulas (P = VI, P = I²R, P = V²/R), energy = P × t, Joule’s heating law
- Magnetic Effects of Electric Current: Fleming’s left-hand rule (motor effect), Fleming’s right-hand rule (generator effect), electromagnetic induction, difference between AC and DC
- Force and Laws of Motion: Newton’s three laws, inertia, momentum (p = mv), impulse, conservation of momentum
- Work, Energy and Power: W = Fs cosθ, kinetic energy = ½mv², potential energy = mgh, conservation of mechanical energy
- Gravitation: Universal law F = Gm₁m₂/r², free fall, distinction between g (acceleration due to gravity) and G (universal gravitational constant)
- Sound: Wave characteristics (frequency, amplitude, wavelength, speed), conditions for echo (minimum distance 17.2 m from the reflecting surface), reflection of sound
- Sources of Energy: Renewable vs non-renewable; properties of solar, wind, hydro and nuclear energy — fact-based questions
Physics Revision Tips:
- Electricity and Light together account for the largest share of Physics questions — give them priority on Day 4
- Practise 5–6 numericals from Electricity (Ohm’s law, parallel circuits, power) and Optics (mirror and lens formula) every day in the last week
- Draw all six standard ray diagrams for concave mirror, convex mirror and lenses from memory — these are directly tested
- Practise Fleming’s rules with the physical hand gesture — muscle memory is faster and more reliable under exam pressure than recalling a text description
Chemistry Revision Strategy for CET Delhi Polytechnic 2026
Chemistry in CET Delhi Polytechnic is largely recall-based — students who have memorised key chemical equations, the reactivity series and properties of common compounds score well. A single focused revision day (Day 5) is sufficient if you revise systematically and write equations by hand rather than just reading them.
High-Priority Topics:
- Chemical Reactions and Equations: Six types of reactions (combination, decomposition, displacement, double displacement, oxidation-reduction), balancing equations by hit-and-trial method
- Acids, Bases and Salts: pH scale (0–14), acid-base indicators (litmus, methyl orange, phenolphthalein), neutralisation reactions, properties of baking soda (NaHCO₃), washing soda (Na₂CO₃) and Plaster of Paris (CaSO₄·½H₂O)
- Metals and Non-metals: Reactivity series (K > Na > Ca > Mg > Al > Zn > Fe > Pb > H > Cu > Hg > Ag > Au), displacement reactions, extraction of metals, corrosion and prevention
- Carbon and Its Compounds: Covalent bonding, functional groups (alcohol −OH, aldehyde −CHO, ketone −CO−, carboxylic acid −COOH), homologous series, IUPAC naming of simple organic molecules, soaps and detergents
- Periodic Classification of Elements: Modern periodic table structure, trends in atomic radius, electronegativity, metallic character and valency across periods and groups
Chemistry Revision Tips:
- Write all key chemical equations on a revision card and read them aloud every morning to build recall through repetition
- Memorise the reactivity series from K (most reactive) down to Au (least reactive) — it underpins all displacement reaction questions
- For Carbon Compounds, practise IUPAC naming of 5–6 molecules daily until naming feels automatic
- Revise pH of common substances: lemon juice (~pH 2), blood (~pH 7.4), baking soda solution (~pH 8.3), bleach (~pH 11) — these are direct recall questions
- Make a compact periodic trends card (radius decreases left-to-right, increases top-to-bottom; electronegativity is opposite) and review it daily
Mock Test and Error Analysis Strategy
Attempting at least one full-length timed mock test before exam day is non-negotiable for CET Delhi Polytechnic 2026. A mock test in real conditions reveals where marks are leaking and gives you data to act on — something no amount of passive revision can provide.
- When to take mocks: Day 6 is the primary mock day; optionally take a 45-question sectional mock on Day 5 evening after finishing Chemistry revision
- Simulate real conditions: Sit at a desk, set a 90-minute timer, keep your phone away and attempt without any reference materials
- Categorise your errors after each mock: Conceptual errors (revise that chapter), calculation mistakes (practise rough-work speed), silly errors (practise re-reading questions carefully before marking)
- With −1 negative marking: An unattempted question scores 0; a wrong answer is a net 5-mark loss against a correct one. Skip questions where you have no idea
- Target accuracy over volume: Attempting 70 questions and getting 65 correct outscores attempting all 90 with 20 wrong answers — internalise this discipline during mock practice
Exam Day Tips for CET Delhi Polytechnic 2026
Your exam performance on June 28 depends on 7 days of preparation — and on how you manage the 90 minutes in the exam itself. Follow these steps to stay calm and score your best.
- Keep your admit card downloaded and your photo ID ready — Aadhaar, passport or school ID. Entry is denied without valid identification
- Check your device, camera and internet connection the evening before — CET Delhi Polytechnic is held in online AI-based proctored mode, so a technical failure at the start time can cost you the attempt
- Log in at least 15 minutes before your scheduled start time to complete the proctoring setup without rushing
- Attempt your strongest subject first to build early momentum; for most students this means beginning with Mathematics
- Target 60 seconds per question — do not spend more than 90 seconds on any single question; mark it and return at the end
- Do not guess randomly — skip questions where you are genuinely unsure, since a wrong answer costs more than leaving it blank
- Night before the exam: 20-minute review of your formula sheet and chemical equations, no new practice after 9 PM, sleep by 10:30 PM
