01Quantitative Aptitude
Quantitative Aptitude in CEPTAM Tech-A checks speed and accuracy across arithmetic and elementary mensuration. Questions are short but time-pressed, so formula recall matters more than long derivation.
342 words, about 2 min02Reasoning and General Intelligence
Reasoning and General Intelligence tests pattern recognition rather than calculation. CEPTAM Tech-A draws on both verbal and non-verbal items: series, analogy, coding-decoding, blood relations, direction sense, ranking, syllogism, seating arrangement, figure series, mirror and water images, and paper folding.
332 words, about 2 min03General Awareness and General Science
General Awareness and General Science blends static GK (polity, history, geography, economy), basic physics, chemistry and biology, plus awareness of Indian defence and space organisations. Science items are usually class-10 level and concept-based rather than numerical.
316 words, about 2 min04English Language
English Language tests standard competitive-exam grammar and usage: error spotting, sentence improvement, fill in the blanks, synonyms and antonyms, idioms, one-word substitutions, sentence ordering and a short comprehension passage. Subject-verb agreement: 'one of + plural noun' takes a singular verb, as in 'One of the boys is absent'.
301 words, about 2 min05Technical Knowledge: Fitter Trade

Electrician Trade covers circuit laws, AC and DC machines, wiring practice, protective devices and safety. Numerical items on Ohm's law and series-parallel networks are common and quick to score.
305 words, about 2 min07Technical Knowledge: Welder, Machinist and Turner Trades
This section combines welding practice with machining on lathe, drilling and milling machines, plus the measurement and safety rules that apply to both. Arc welding uses a consumable electrode; the flux coating shields the molten pool.
334 words, about 2 min08Technical Knowledge: Electronics, Instrumentation and Computer Trades
This section spans semiconductor devices, digital electronics, measurement and instrumentation, and computer fundamentals. Expect short numerical items on transistor currents, logic gates and number systems.
