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 1 is the same paper for every student, so your rank is among everyone who sat it. Difficulty: 32% easy, 58% medium, 11% hard.
Sample questions from Mock 1 with answers
10 of the 180 questions, with answers and explanations. The rest are in the app.
Question 1
Biology · Sexual Reproduction in Flowering PlantsThe most common type of ovule, in which the micropyle and the funicle lie close together because the body is inverted, is:
- A anatropous
- B campylotropous
- C hemitropous
- D orthotropous
Answer: A. anatropous
Why: It is the curved type found in most angiosperms.
Question 2
Biology · Body Fluids and CirculationThe lymphocytes of the two major types, the B and T forms, are responsible for:
- A oxygen transport
- B digestion
- C the immune responses of the body
- D the blood clotting
Answer: C. the immune responses of the body
Why: They are about 20–25% of the WBCs.
Question 3
Biology · Digestion and AbsorptionThe hepatopancreatic duct is guarded by the:
- A the ileocaecal valve
- B pyloric sphincter
- C cardiac sphincter
- D sphincter of Oddi
Answer: D. sphincter of Oddi
Why: It opens into the duodenum.
Question 4
Biology · Molecular Basis of InheritanceThe central dogma of molecular biology, as proposed by Francis Crick, states that:
- A RNA is made from protein
- B information flows from DNA to RNA to protein
- C DNA is made from protein
- D information flows from protein to DNA
Answer: B. information flows from DNA to RNA to protein
Why: Reverse transcription in retroviruses shows that information can also flow from RNA to DNA.
Question 5
Biology · Mineral NutritionA plant showing interveinal chlorosis in young leaves, with veins remaining green, most likely suffers a deficiency of:
- A nitrogen
- B iron
- C potassium
- D phosphorus
Answer: B. iron
Why: Iron is immobile within the plant and is essential for chlorophyll synthesis, so its deficiency shows first as interveinal chlorosis in the youngest leaves.
Question 6
Physics · Dual Nature of Radiation and MatterIf the maximum kinetic energy of photoelectrons is 3 eV, the stopping potential is:
- A 1.5 V
- B 0.3 V
- C 6 V
- D 3 V
Answer: D. 3 V
Why: eV₀ = K_max, so V₀ = 3 V.
Question 7
Physics · Mechanical Properties of SolidsThe extension of a heavy wire hanging vertically under its own weight is proportional to:
- A the cube of its length
- B its length
- C the square of its length
- D its radius
Answer: C. the square of its length
Why: Δl = ρgL²/2Y.
Question 8
Chemistry · General Principles and Processes of Isolation of ElementsA reduction of a metal oxide is feasible thermodynamically when:
- A the ΔG° of the overall coupled reaction is negative
- B ΔH° is zero
- C ΔS° is zero
- D ΔG° is positive
Answer: A. the ΔG° of the overall coupled reaction is negative
Why: The two reactions are coupled, and their free energy changes are added.
Question 9
Chemistry · p-Block ElementsAmong the Group 13 elements, the one that is used in making a metal that melts in the hand at about 30 °C is:
- A boron
- B indium
- C gallium
- D aluminium
Answer: C. gallium
Why: Its low melting point (29.8 °C) is unusual for a metal.
Question 10
Chemistry · p-Block ElementsThe most abundant noble gas in the atmosphere is:
- A neon
- B argon
- C krypton
- D helium
Answer: B. argon
Why: It makes up about 0.93% of dry air.
