VITEEE 2020 Paper Pattern

The planned 2020 exam had 125 multiple-choice questions in 150 minutes. Students would answer Mathematics or Biology along with Physics, Chemistry, English and Aptitude. Each question had four choices, with one answer to be selected. The paper was in English, with no negative marking.

Mathematics or Biology had the largest share at 32%. Physics and Chemistry together made up 56%, while English and Aptitude accounted for the remaining 12%. This was the announced pattern before the exam was cancelled.

The VITEEE exam pattern explains the later format and marking rules. The short subject papers on this page are better suited to chapter practice than a full-length timed attempt.

VITEEE 2020 Subject-Wise Questions

Physics

The 10 Physics questions cover force balance, the ideal-gas equation, electric fields, a potentiometer, magnetic fields, LCR circuits, lenses, the photoelectric effect, radioactivity and semiconductors. Electricity and magnetism, including the LCR question, account for four questions.

In the LCR problem, the inductor and capacitor each have a voltage of 50 V. Their voltages are opposite in phase, so the voltage across the LC combination is zero, not 100 V. The radioactivity question is shorter: after two half-lives, 25% remains. For a half-life of 1,600 years, that takes 3,200 years.

Chemistry

The 10 Chemistry questions include atomic structure, bonding, entropy, electrochemistry, stereochemistry, alcohols, carbonyl reactions and biomolecules. Five concern organic chemistry or biomolecules; the others cover physical and inorganic concepts, including an X-ray question.

The Bohr-model question uses a one-electron lithium ion. Its ground-state binding energy is 13.6 × 3², giving 122.4 eV. Other questions test whether you can identify oxidation at the anode and choose the reagent needed for a conversion.

For the Grignard-reagent question, an alkyl nitrile forms an intermediate that gives a ketone on hydrolysis. In the alcohol question, boiling point increases in the order methanol, isopropyl alcohol and n-propyl alcohol.

Mathematics

Mathematics has 10 questions covering simultaneous equations, trigonometry, conics, vectors, three-dimensional geometry, limits, integration, differential equations, probability and logic. Calculus and geometry with vectors each contribute three questions.

The sphere question can be solved through its centre. The centre is (1/2, 0, 1), and one end of a diameter is (1, 1, 0). The other end is (0, -1, 2). For the probability question, use the binomial distribution with a success probability of 1/4 because both coins must show heads.

Biology

The 10 Biology questions cover animal classification, meiosis, embryonic development, genetic disorders, immunity, enzymes, photosynthesis, respiration and ecology. They mostly test the difference between closely related terms or processes.

For example, synapsis occurs between homologous chromosomes. An apoenzyme is the protein part of an enzyme, while the complete active enzyme, including its required non-protein component, is a holoenzyme. The C4-plant question tests why photorespiration is suppressed rather than frequent.

The VITEEE syllabus includes the wider Biology units as well as the Mathematics, Physics and Chemistry topics. These short papers cover selected questions from those subjects.

English

The English paper has two questions: one on a figure of speech in poetry and another on syllables. The first asks you to identify a metaphor. The second uses the word personification to test how its sounds are divided.

Aptitude

The five Aptitude questions cover a data table, data sufficiency, letter coding, syllogisms and clock angles. In the data-sufficiency problem, each statement separately establishes that the integer is even. You do not need both statements together.

The clock question asks about the hour hand moving from 10 a.m. to 3 p.m. It moves 30 degrees per hour, so the rotation is 150 degrees. In the coding question, the first half of the word moves one letter forward and the second half moves one letter back.

Topic-Wise Coverage and Difficulty

The Mathematics paper gives equal space to calculus and geometry with vectors. The counts below refer to its 10 practice questions, not a fixed chapter-wise weightage for the exam.

The questions vary in the amount of calculation needed. The lens and semiconductor problems require formulas and careful substitution. Mathematics includes longer tasks such as finding an enclosed area and solving a differential equation. Biology and English are mainly concept and language questions. Since the 2020 exam was cancelled, there is no actual shift-wise difficulty rating for that year.

Answer Explanations for Physics and Mathematics

Some answer labels in the linked solutions differ from the calculations. Use these results for the questions listed below. The lens question gives approximately 76.92 cm, which is not an exact match for any option; the rotating-charge question also has an option mismatch.

For Mathematics Q8, differentiating sin x tan y + 2 sin(x + y) gives the two coefficients in the question. For Q10, the contradiction is between the truth values of p AND NOT r and q; negating the first expression changes it to p → r. This gives option A.

How to Revise With These Papers

If you miss the LCR question, revise phase differences before solving another circuit problem. For the ideal-gas and semiconductor questions, check the unit conversion and powers of ten. In Mathematics, group the limit, area and differential-equation questions as a calculus session, then attempt the geometry and vector questions separately.

The VITEEE preparation guide covers subject-wise revision and mock review. For a longer paper after these short sets, the VITEEE 2021 question papers include an 80-question compilation as well as slot-wise questions.
