A full-length NEET mock in the real pattern: 90 Biology, 45 Physics and 45 Chemistry questions, +4 for a correct answer and −1 for a wrong one. Mock 11 is the same paper for every student, so your rank is among everyone who sat it. Difficulty: 32% easy, 59% medium, 9% hard.
Sample questions from Mock 11 with answers
10 of the 180 questions, with answers and explanations. The rest are in the app.
Question 1
Biology · Transport in PlantsWhich of the following is true of the active transport?
- A It is the same as diffusion
- B It is carried out by the membrane proteins and needs ATP
- C It occurs along the gradient
- D It needs no energy
Answer: B. It is carried out by the membrane proteins and needs ATP
Why: It is an uphill transport.
Question 2
Biology · Animal KingdomThe largest phylum of the animal kingdom is:
- A Arthropoda
- B Chordata
- C Mollusca
- D Annelida
Answer: A. Arthropoda
Why: Over two-thirds of all the named species on earth are the arthropods.
Question 3
Biology · Reproductive HealthThe lactational amenorrhea method is effective as a natural contraceptive only up to about:
- A one year
- B two years
- C six months after parturition
- D one week
Answer: C. six months after parturition
Why: It works while the mother is exclusively breastfeeding, as ovulation and the cycle do not resume.
Question 4
Biology · Reproductive HealthOral contraceptive pills contain:
- A thyroxine
- B only testosterone
- C progestogen alone or in combination with oestrogen
- D only FSH
Answer: C. progestogen alone or in combination with oestrogen
Why: They inhibit ovulation and implantation, and alter the cervical mucus.
Question 5
Biology · EvolutionThe use of weedicides and pesticides leading to the evolution of resistant varieties is evidence of:
- A artificial selection
- B spontaneous generation
- C Lamarck's theory only
- D natural selection acting in a short period of time
Answer: D. natural selection acting in a short period of time
Why: Antibiotic resistance in bacteria is another example.
Question 6
Physics · Units and MeasurementsThe percentage errors in the measurement of the mass and the volume of an object are 2% and 3%. The maximum percentage error in the density is:
- A 5%
- B 1%
- C 6%
- D 1.5%
Answer: A. 5%
Why: ρ = m/V, so the relative errors add: 2 + 3 = 5%.
Question 7
Physics · WavesIn a standing wave, points that never move are called:
- A antinodes
- B nodes
- C crests
- D troughs
Answer: B. nodes
Why: Nodes are points of zero displacement formed by destructive interference of the two component waves; antinodes are points of maximum displacement.
Question 8
Chemistry · Environmental ChemistryStrategies to reduce soil pollution include:
- A dumping waste in rivers
- B waste recycling and the use of biodegradable material
- C burning plastic
- D using more pesticides
Answer: B. waste recycling and the use of biodegradable material
Why: Recycling reduces the volume of waste going to landfills.
Question 9
Chemistry · EquilibriumWhich of the following is a Lewis acid?
- A NH₃
- B H₂O
- C OH⁻
- D BF₃
Answer: D. BF₃
Why: BF₃ has an empty p orbital and accepts an electron pair.
Question 10
Chemistry · Surface ChemistryPhysical adsorption generally:
- A is independent of temperature
- B decreases with a rise in temperature
- C involves the formation of chemical bonds
- D increases with a rise in temperature
Answer: B. decreases with a rise in temperature
Why: Adsorption is exothermic, so by Le Chatelier's principle it is favoured at low temperature.
