1Which SI unit is used to measure electric current?

A.Ampere

B.Volt

C.Ohm

D.Watt

Explanation: Electric current is the rate of flow of charge and is measured in amperes (A) in the SI system. Voltage is potential difference in volts, resistance in ohms, and power in watts.

2What is the chemical formula of water?

A.CO2

B.H2O

C.NaCl

D.H2O2

Explanation: Water consists of two hydrogen atoms bonded to one oxygen atom, written H2O. CO2 is carbon dioxide, NaCl is common salt, and H2O2 is hydrogen peroxide.

3Which organelle is known as the powerhouse of the cell?

A.Nucleus

B.Ribosome

C.Mitochondrion

D.Golgi apparatus

Explanation: Mitochondria produce ATP through cellular respiration and are therefore called the powerhouse of the cell. The nucleus stores genetic material, ribosomes synthesize proteins, and the Golgi apparatus packages and ships cellular products.

4The process by which green plants prepare food using sunlight is called:

A.Respiration

B.Transpiration

C.Fermentation

D.Photosynthesis

Explanation: Photosynthesis converts carbon dioxide and water into glucose and oxygen using chlorophyll and sunlight. Respiration releases energy from food, transpiration is water loss from leaves, and fermentation is anaerobic breakdown of sugars.

5Which of the following is a non-metal that exists as a liquid at room temperature?

A.Bromine

B.Sodium

C.Mercury

D.Iron

Explanation: Bromine is a non-metal that is liquid at ordinary room temperature. Mercury is also liquid but is a metal. Sodium and iron are solid metals under normal conditions.

6Newton's third law of motion states that:

A.Force equals mass times acceleration

B.Every action has an equal and opposite reaction

C.A body continues in uniform motion unless acted upon by a force

D.Momentum is always conserved in all situations

Explanation: Newton's third law states that for every action force there is an equal and opposite reaction force. F = ma is the second law, and inertia/uniform motion is the first law. Momentum conservation needs isolated systems and is not the wording of the third law.

7Which acid is present in vinegar?

A.Citric acid

B.Lactic acid

C.Acetic acid

D.Sulphuric acid

Explanation: Vinegar is a dilute aqueous solution of acetic acid (ethanoic acid). Citric acid is found in citrus fruits, lactic acid in sour milk and muscle fatigue chemistry, and sulphuric acid is a strong mineral acid used industrially, not in food vinegar.

8The SI unit of frequency of a vibrating body is:

A.Decibel

B.Newton

C.Pascal

D.Hertz

Explanation: Frequency is the number of oscillations per second and is measured in hertz (Hz). Decibel measures sound intensity level, newton is force, and pascal is pressure.

9Which blood group is called the universal donor in ABO system (red-cell transfusion without considering Rh)?

A.O

B.A

C.B

D.AB

Explanation: Group O red cells lack A and B antigens, so they are least likely to trigger ABO agglutination in recipients and are called the universal donor for red-cell transfusion in the ABO system. Group AB is the universal recipient for ABO red-cell transfusion because AB plasma lacks anti-A and anti-B antibodies; groups A and B each have one of those antibodies.

10pH of a neutral solution at 25°C is:

A.0

B.7

C.14

D.1

Explanation: At 25°C, pure water has equal H+ and OH− concentrations and a pH of 7, defined as neutral. Values below 7 are acidic and above 7 are basic. pH 0 and 1 are strongly acidic; pH 14 is strongly basic.

About the DRDO CEPTAM Tech-A Exam

The DRDO CEPTAM Technician-A (Tech-A) examination recruits ITI-qualified technicians into the Defence Research & Development Organisation Technical Cadre (DRTC) at Pay Level-2 (₹19,900–₹63,200 as per 7th CPC in CEPTAM-11). Candidates face a common Tier-I aptitude/science CBT, a Tier-II trade-oriented CBT with a short personality test, and a qualifying hands-on Trade Test. Post-codes span trades such as electrician, fitter, electronics, COPA and others listed in each advertisement.

Assessment

Technician-A selection (CEPTAM-11): Tier-I CBT screening common to all post-codes — General Science (40), General English (30), Quantitative Aptitude/General Maths (40), General Intelligence & Reasoning (40) — 150 Q / 150 marks / 120 minutes; all CBT sections are individually time-bound and lock when their allotment ends (CEPTAM-11 §4.1 / FAQ). Tier-II CBT for provisional shortlisting for Trade Test — Part I Personality Test (20 minutes) and Part II subject/trade-specific test (120 Q / 120 marks / 90 minutes). Then a qualifying ITI-level Trade Test specific to the post-code (DGT syllabus). Negative marking: 0.25 marks per wrong answer in Tier-I and Tier-II Part II (official FAQ).

Time Limit

Tier-I: 120 minutes total with individually time-bound sections (locked when allotment ends). Tier-II Part II: 90 minutes (Personality Test Part I: 20 minutes). Trade Test duration varies by trade as notified on the admit card.

Passing Score

Minimum qualifying marks for Tier-I and Tier-II Part II: 40% (UR/OBC/EWS) and 35% (SC/ST/PwBD). Trade Test is mandatory and qualifying: 50% (UR/OBC/EWS) and 45% (SC/ST/PwBD) per CEPTAM-11 advt. Merit for provisional selection is based on Tier-II Part II after Trade Test qualification.

Exam Fee

Technician-A (CEPTAM-11): General/OBC/EWS/MSP — ₹100 (non-refundable) + ₹500 (refundable) = ₹600 total; Women/SC/ST/PwBD/Ex-Servicemen (as defined) — Nil + ₹500 = ₹500. Refundable fee returned only if the candidate appears in Tier-I. Confirm on the live advertisement for your cycle.

DRDO CEPTAM Tech-A Study Tips from Top Performers

1Drill each Tier-I section against the clock—CEPTAM-11 locks a section when its allotted time ends (150 questions in 120 minutes total across four timed sections)—and practice skipping rather than guessing because of 0.25 negative marking.

2Keep General Science revision Class-10 NCERT-level across physics, chemistry and biology rather than over-specialising in one trade—Tier-I is common to all Tech-A post-codes.

3After clearing Tier-I mocks, shift time to your post-code ITI theory for Tier-II Part II and practical Trade Test skills; provisional merit hinges on the subject paper once you qualify the Trade Test.

Frequently Asked Questions

What is the DRDO CEPTAM Technician-A Tier-I exam pattern?

As per CEPTAM-11 Table-2, Tier-I is a 150-question, 150-mark CBT in 120 minutes covering General Science (40), General English (30), Quantitative Aptitude/General Maths (40) and General Intelligence & Reasoning (40). There is negative marking of 0.25 per wrong answer.

Is there a Trade Test for Technician-A?

Yes. After Tier-II CBT shortlisting, Technician-A candidates must qualify an ITI-level Trade Test specific to their post-code (DGT syllabus). The Trade Test is qualifying in nature; provisional merit uses Tier-II Part II scores among those who qualify.

What application fee applied for CEPTAM-11 Technician-A?

General/OBC/EWS/MSP candidates paid ₹100 non-refundable + ₹500 refundable (₹600 total). Women/SC/ST/PwBD/Ex-Servicemen (as defined in the advt) paid ₹500 refundable only. The refundable amount is returned only if you appear in Tier-I. Always confirm the fee table in the live advertisement.

How does this 100-question practice bank map to the real exam?

This bank focuses on Tier-I's four common sections, weighted to the official 40:30:40:40 split (±2%). It does not replace Tier-II trade-specific theory or the hands-on Trade Test—revise your ITI trade syllabus separately for those stages.
