VITEEE 2022 Paper Structure and Section-Wise Weightage
VITEEE 2022 had 125 multiple-choice questions and a duration of 150 minutes. Mathematics or Biology carried the largest share, followed by Physics and Chemistry. English and Aptitude together accounted for 15 questions.
| 2022 section | Questions | Share |
|---|
| Mathematics or Biology | 40 | 32% |
| Physics | 35 | 28% |
| Chemistry | 35 | 28% |
| Aptitude | 10 | 8% |
| English | 5 | 4% |
| Total | 125 | 100% |
The Mathematics paper below covers the PCM route. Students taking Biology can use the common Physics, Chemistry, English and Aptitude questions, then practise Biology separately. The VITEEE 2021 question paper follows a shorter, 80-question format, so its total marks and duration differ.
VITEEE 2022 Subject-Wise Question Analysis
The VITEEE 2022 questions and solutions cover numerical problems, reaction-based questions, geometry, reasoning and comprehension. The analysis below refers to the combined paper.
Physics
Physics includes Brownian motion, simple harmonic motion, interference, electrostatics, electromagnetic induction, atomic physics and semiconductors. Mechanics questions cover momentum, circular motion, central forces, escape velocity and equilibrium. Some questions ask for a direct relation; others combine two concepts.
In the water-droplet question, the electric force balances the droplet's weight. Using qE = mg, a mass of 0.1 g and an electric field of 4.9 × 105 N/C give a charge of 2 × 10-9 C. The mass must be converted to kilograms before substitution.
The interference question gives light intensities in the ratio 9:4. Their amplitudes are in the ratio 3:2, so the maximum-to-minimum intensity ratio is (3 + 2)2:(3 - 2)2, or 25:1. Using the intensity ratio directly in place of amplitude gives the wrong result.
Chemistry
Chemistry covers equilibrium, solutions, atomic structure, chemical bonding, periodic trends, organic reactions, biomolecules and polymers. The paper includes conjugate acids and bases, non-reducing sugars, nucleotide components, coordination numbers and electrochemical conductivity.
One equilibrium question asks for the decomposition constant of methanol, even though the reaction is initially shown in the formation direction. For CH3OH → CO + 2H2, the given partial pressures give Kp = 1 × (0.1)2 / 2 = 0.005 atm2. Reversing the reaction changes which concentrations or pressures go in the numerator.
Organic questions test both reactions and their underlying concepts. Carboxylic acids are more acidic than alcohols because their conjugate bases are resonance-stabilised. In the carbon-carbon bond question, the Cannizzaro reaction differs from Wurtz and Friedel-Crafts reactions: it involves oxidation and reduction of an aldehyde rather than forming a new carbon-carbon bond.
Mathematics
Mathematics includes sets, relations, complex numbers, sequences, coordinate geometry, continuity, integration, matrices, determinants and probability. Geometry has a substantial presence, with questions on straight lines, circles, parabolas, ellipses, hyperbolas and three-dimensional coordinates.
The dice question asks for a perfect-square sum. With two ordinary dice, the possible square sums are 4 and 9. There are three ordered outcomes for 4 and four for 9, giving a probability of 7/36.
Calculus questions include continuity at a joining point, area under a curve and definite integrals. For a piecewise function, equate the left-hand and right-hand values at the joining point before solving for the constants. In geometry, completing the square helps identify the centre and axes of a conic.
English and Aptitude
English includes comprehension, pronunciation, syllables and idioms. The questions refer to Sadao's treatment of a patient and Gandhi's work in Champaran. The idiom “a bolt out of the blue” means something completely unexpected.
Aptitude includes number series, coding, directions, clocks, syllogisms and data sufficiency. In a data-sufficiency question, ratios alone may not establish actual ages. For example, knowing two people's ages are in the ratio 3:4 does not give their ratio four years earlier unless their ages or another independent condition is known.
Important Topics in the 2022 Paper
Coordinate geometry and three-dimensional coordinates appear in 12 questions; calculus appears in six. These are counts from the combined paper, not fixed chapter-wise weightage for every 2022 shift.
| Mathematics topic group | Questions in the combined paper |
|---|
| Coordinate geometry and three-dimensional coordinates | 12 |
| Calculus | 6 |
| Probability and statistics | 3 |
The geometry count includes questions 81-87 and 100-104. The calculus count includes questions 88, 89, 94, 95, 107 and 108. Probability and statistics appear in questions 90, 91 and 110. Use the VITEEE syllabus to cover the wider topic list rather than restricting revision to these chapters.
VITEEE 2022 Difficulty Level
Student feedback described VITEEE 2022 as moderate overall. Mathematics was reported as lengthy and moderately difficult, Physics as moderate, and Chemistry as easy to moderate. English and Aptitude were generally considered easier. Difficulty varied across shifts.
The combined paper contains both short concept questions and multi-step calculations. Chemistry includes direct questions on sugars and periodic trends alongside equilibrium calculations. Mathematics requires more calculation in conics, integration and determinants. A useful review is to separate an incorrect formula from a calculation error; the same revision will not fix both. The VITEEE preparation guide covers subject-wise practice and mock-test review.
VITEEE 2022 July Question Papers
1 July Questions
The 1 July memory-based paper includes picric acid, acrolein, flame tests, radioactivity, probability and area between curves. A coin-toss question asks for at least four heads in six tosses. For a fair coin, add the probabilities of four, five and six heads: (15 + 6 + 1) / 64 = 11/32.
The area question uses y = x2 and y = 8 - x2. The curves meet at x = -2 and x = 2. Integrating their difference, 8 - 2x2, between those limits gives 64/3 square units.
2 July Questions
The 2 July memory-based questions include the photoelectric effect, forward bias, electronegativity, crystal defects, carbohydrates and calendars. Biology topics include the smooth endoplasmic reticulum and rhizomes.
For the crystal-defect question, a Schottky defect reduces density because ions are missing from the crystal. A Frenkel defect leaves density unchanged because an ion moves to an interstitial position without leaving the crystal.
Calendar answer: 29 February falls on a Monday in 2016, 2044 and 2072 within the stated period. That gives three occurrences including 2016, or two birthdays after the birth year. The four-occurrence answer in the linked solution is incorrect.
VITEEE 2022 Marking Scheme
The 2022 marking scheme awarded 1 mark for each correct answer, with no negative marking. Wrong and unanswered questions earned zero.
| 2022 response | Marks |
|---|
| Correct answer | +1 |
| Wrong answer | 0 |
| Unanswered | 0 |
In a complete 125-question attempt, 90 correct answers give 90/125, or 72%. If 110 questions were attempted, accuracy is 90/110, or 81.8%. For a shorter practice set, calculate the percentage using the number of questions in that set.
The VITEEE exam pattern covers newer rules. Keep this historical score separate from a score calculated using a later marking scheme; neither a practice percentage nor accuracy gives an exact rank.
Answer Clarifications
Physics Q11: The electric-field amplitude is 6 V/m along the z-axis, not the x-axis. The wave travels along the x-axis and its magnetic field is along the y-axis, so the electric field must be perpendicular to both.
Aptitude Q117: From 8 AM to 8 PM, the hour hand completes one full rotation: 360°. The listed options do not include this value; 180° would correspond to six hours.
