DRDO CEPTAM Tech-A study plan

DRDO CEPTAM Tech-A · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Quantitative Aptitude & Technical Knowledge: Fitter Trade

Memorise and recite SI base units, derived units and common prefixes, then apply them to 25 unit-conversion drills
Read and interpret vernier calliper and micrometer readings from 20 written descriptions of scale and thimble positions
Build a one-page formula sheet for domain 1 covering percentage, profit-loss and simple/compound interest

A dated 60-question arithmetic set scored and error-logged, plus a completed formula sheet with 15 worked examples

Week 2

Solve 45 questions on time-work, pipes-cisterns and time-speed-distance with a written step for each
State Ohm's law, state the power equations and compute 30 circuit values for series and parallel resistor combinations
Distinguish AC and DC fundamentals by writing definitions and solving 15 RMS, frequency and reactance numericals
Log every wrong answer with its cause category (concept, calculation, misread)

A 45-question mixed set with a categorised error log showing at least 3 recurring error patterns

Week 3

Solve 40 mensuration and geometry questions covering area, volume, surface area and circle properties
Solve 30 data-interpretation and simplification questions under a 20-minute timer
Explain fits and tolerances (clearance, interference, transition) in writing with one worked hole-shaft example each
Identify and describe 20 hand tools and measuring instruments from written specifications alone

A timed 50-question quantitative mock scored, with a written summary of the two weakest sub-topics and a fix plan

Week 4

Solve 60 reasoning questions across series, analogy, coding-decoding and blood relations
Complete 25 seating-arrangement and 15 syllogism questions using diagram notation
Draw and analyse 8 circuits (star-delta, series-parallel, lamp and motor control) and compute current, voltage and power at each node
Write the safety procedure for earthing, insulation resistance testing and shock first response

A reasoning accuracy report by question type (target 70 percent or better) and a hand-drawn circuit analysis set of 8 solved diagrams

Week 5

Solve 40 non-verbal questions on figure series, mirror images, paper folding and embedded figures
Solve 20 statement-conclusion and 15 direction-sense questions with reasoning shown

Compare lathe operations (turning, facing, threading, taper turning) and write the setup for each

A 60-question reasoning mock scored at 75 percent or better, plus a one-page machining-parameters summary with a worked speed calculation

Week 6

Describe welding processes (arc, gas, TIG, MIG, resistance) and their electrode, polarity and application differences in writing
Explain machinability, tool materials and drill geometry, then answer 30 trade questions on them
Revise general science: state 25 physics and chemistry facts (laws, SI quantities, common reactions) and self-test them
Cover static and current affairs from the past six months by writing 30 short notes

A 40-question mixed trade and general-science test scored, with a corrected answer sheet for every wrong item

Week 7

Complete 30 error-spotting and 20 sentence-improvement questions, recording the grammar rule violated each time
Practise 15 cloze and 10 reading-comprehension passages under time pressure, summarising the main idea of each
Explain diode, transistor and op-amp basics and solve 20 numericals on gain, rectification and logic gates
Define 25 computer and instrumentation terms (sensor, transducer, PLC, bus, memory) accurately

A grammar-rule log of 20 rules with one example each, plus a 25-term technical glossary written from memory

Week 8

Take 3 full-length timed mocks under exam conditions and score each section separately
Re-solve every question missed in weeks 1 to 7 and confirm each is now correct
Revise all formula sheets, trade summaries and error logs in three 90-minute passes
Rehearse section-wise time allocation and question-skipping strategy on the final mock

Three scored full mocks with a section-wise trend table showing improvement from mock 1 to mock 3

Week 2: Arithmetic and electricity fundamentals: score 60 percent or better on a 30-question combined set drawn from domains 1 and 6

Week 4: Reasoning accuracy at 70 percent or better across 60 mixed questions, and 8 circuits solved with correct current and power values

Week 6: Trade knowledge at 65 percent or better on a 40-question set spanning fitter, electrician and machinist content

Week 8: Final mock at or above the expected cut-off in every section, with no section below 50 percent
