JASSO administers EJU Science as an 80-minute, multiple-choice basic academic abilities test scored 0-200. Candidates select two subjects from Physics, Chemistry, and Biology on exam day, according to the requirements of the universities and programs they plan to apply to. The 2026 EJU applies revised Science syllabuses from the 1st Session, covering high-school Basic and Advanced Physics, Chemistry, and Biology topics. This local bank provides 100 original practice questions across all three sciences.

Sample EJU Science Practice Questions

Try these sample questions to test your EJU Science exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A cart starts from rest and accelerates uniformly at 2.0 m/s^2 for 3.0 s. What is its speed at the end of the interval?
A.3.0 m/s
B.6.0 m/s
C.9.0 m/s
D.12 m/s
Explanation: For uniformly accelerated motion, final speed is v = v0 + at. The cart starts from rest, so v0 = 0, and v = 0 + (2.0)(3.0) = 6.0 m/s. This is a direct use of the kinematics relationships in the mechanics section of the EJU Science syllabus.
2A 4.0 kg block is pulled horizontally by a net force of 12 N. What is the block acceleration?
A.0.33 m/s^2
B.3.0 m/s^2
C.16 m/s^2
D.48 m/s^2
Explanation: Newton second law gives F = ma, so a = F/m = 12 N / 4.0 kg = 3.0 m/s^2. The key phrase is net force; no extra friction force needs to be subtracted unless the problem gives one.
3Which quantity is equal to the work done by a constant force parallel to the displacement?
A.Force times displacement
B.Mass times velocity
C.Pressure times volume only for solids
D.Charge times current
Explanation: When a constant force acts in the same direction as the displacement, work is W = Fd. More generally W = Fd cos theta, but here theta = 0 so cos theta = 1. Work-energy relationships are a core mechanics topic.
4A ball experiences an impulse of 5.0 N s. What is the change in its momentum?
A.1.0 kg m/s
B.2.5 kg m/s
C.5.0 kg m/s
D.25 kg m/s
Explanation: Impulse equals change in momentum: J = delta p. Therefore an impulse of 5.0 N s gives a momentum change of 5.0 kg m/s, since 1 N s is equivalent to 1 kg m/s.
5A substance with a larger specific heat capacity requires which condition to raise its temperature by the same amount?
A.Less heat for the same mass
B.More heat for the same mass
C.A lower absolute temperature
D.No heat transfer
Explanation: Specific heat capacity is the heat needed to raise 1 kg of a substance by 1 K. From Q = mc delta T, for the same mass and same temperature change, a larger c requires a larger Q. This explains why water changes temperature slowly compared with many solids.
6For a fixed amount of ideal gas at constant volume, what happens to pressure when absolute temperature doubles?
A.Pressure is halved
B.Pressure stays the same
C.Pressure doubles
D.Pressure becomes four times larger
Explanation: At constant volume and fixed amount of gas, the ideal gas law PV = nRT gives P proportional to T. If absolute temperature doubles, pressure doubles. The word absolute matters; temperatures must be in kelvin, not Celsius.
7A wave has frequency 50 Hz and wavelength 2.0 m. What is its speed?
A.25 m/s
B.52 m/s
C.100 m/s
D.2500 m/s
Explanation: Wave speed is v = f lambda. Substituting f = 50 Hz and lambda = 2.0 m gives v = 100 m/s. The relationship applies to mechanical waves and electromagnetic waves when the correct medium speed is used.
8Two sound waves of slightly different frequencies are heard together. What phenomenon causes a periodic rise and fall in loudness?
A.Diffraction
B.Beats
C.Polarization
D.Total internal reflection
Explanation: Beats occur when two sound waves with nearby frequencies interfere, producing alternating constructive and destructive interference. The beat frequency equals the absolute difference between the two frequencies. This is included in the EJU sound-wave scope.
9A 6.0 ohm resistor has a current of 2.0 A through it. What is the voltage across the resistor?
A.3.0 V
B.4.0 V
C.8.0 V
D.12 V
Explanation: Ohm law gives V = IR. With I = 2.0 A and R = 6.0 ohm, V = 12 V. The same relationship is used throughout direct-current circuit questions.
10In the photoelectric effect, increasing the intensity of light above the threshold frequency mainly increases what?
A.The number of emitted electrons per second
B.The maximum kinetic energy of each electron
C.The work function of the metal
D.The threshold frequency of the metal
Explanation: For light whose frequency is above threshold, higher intensity means more photons arrive each second, so more electrons can be emitted per second. The maximum kinetic energy depends on photon frequency, not intensity. The work function and threshold frequency are properties of the material.

EJU Science Study Tips from Top Performers

1Confirm the exact Science subject pair required by each target university before you choose what to study deeply.
2Practice the two selected subjects together so you build pacing for the official 80-minute Science session.
3Memorize core formulas in mechanics, electricity, ideal gases, stoichiometry, acid-base chemistry, and genetics, then practice applying them rather than only recalling them.
4Use wrong-answer explanations to classify mistakes as concept gaps, formula selection errors, unit errors, or reading errors.
5For Chemistry and Physics calculations, write units at each step because many EJU-style distractors come from unit conversion or ratio mistakes.
6For Biology, connect vocabulary to mechanisms: DNA to RNA to protein, hormone to response, stimulus to nerve signal, and ecosystem process to matter or energy flow.

Frequently Asked Questions

How many EJU Science subjects do I take?
