At most IT walk-ins the aptitude test comes first, and it's a brutal filter — a big share of candidates are knocked out here before anyone ever looks at their resume or talks to them. The upside is that this round is the most beatable of all, because it's predictable: the formulas are finite, the patterns repeat, and companies like TCS, Infosys, and Wipro reuse question types year after year. Prepare for a few weeks and you clear a round that most people walk in and fail cold.

Know the test you're sitting for
The big companies run named tests — TCS NQT, Infosys's aptitude-plus-coding round, Wipro's NLTH, HCL TechBee, Cognizant's GenC — and while details differ, the shape is similar: quantitative ability, logical reasoning, verbal ability, and sometimes basic programming MCQs, usually 50–80 questions in 60–90 minutes with sectional cutoffs. The one detail that changes your strategy is negative marking: most of these dock you for wrong answers, so blind guessing actively hurts your score. Find out your target company's format before you start, because prep is much more effective when it's aimed.
Pro Tip: Pull previous-year papers for your specific company from PrepInsta or IndiaBix. These tests recycle patterns heavily, so company-specific practice is the single highest-return thing you can do.
Quant: drill the topics that actually show up
You don't need all of school maths — a focused list covers the vast majority of questions. Prioritise number systems (HCF/LCM, remainders, divisibility), percentages, profit and loss, time and work, time-speed-distance, ratios and proportions, averages and mixtures, and basic probability and permutations. For each, learn the shortcut method rather than the long derivation, then grind 20–30 questions until it's automatic. Speed matters as much as correctness here, because the clock is the real opponent — knowing a formula slowly is almost as bad as not knowing it.
Reasoning: pattern practice, not maths
Logical reasoning needs no advanced maths, just pattern familiarity, which is pure practice. Cover coding-decoding, number and letter series, seating arrangements (linear and circular), blood relations (draw the family tree every time), directions, and syllogisms (Venn diagrams make these easy). Data interpretation — reading tables and graphs — also sits here. The tactical bit: seating arrangements and DI eat time, so leave them for last and bank the quick wins first. Give yourself a fixed budget per question and move on the moment one turns into a swamp.
Pro Tip: Do a couple of full, timed mock tests a week — free ones on Testbook or Oliveboard work. Practising under a clock is what stops you from freezing at the actual venue.
Verbal: the section people underprepare
Verbal checks basic English — reading comprehension, sentence correction, fill-in-the-blanks, synonyms/antonyms, and para-jumbles. It's the section candidates most often ignore and then lose the cutoff on. The fix is slow but reliable: read one English editorial a day (The Hindu's is a favourite for vocabulary and comprehension practice), revise the common grammar rules (subject-verb agreement, tenses, articles, modifiers), and do a few sentence-correction questions daily. Because verbal improves gradually rather than overnight, it's the section to start earliest.
Managing the clock and the negative marking
There's a specific kind of panic in that test hall — the timer counting down on screen, and the person two seats over already clicking through like they've seen the paper before (they haven't; ignore them). How you move through the paper matters as much as what you know. Do a first pass grabbing every easy and medium question across all sections, skipping anything that runs past your per-question budget; then a second pass for the ones you parked. Keep negative marking front of mind: a wrong answer cancels a right one, so if you can't eliminate at least two options, leave it blank rather than gamble. Clearing the cutoff comfortably beats chasing a perfect score and running out of time — nobody gets a bonus for finishing early.
A month's plan and the free resources to use
You don't need paid coaching. A workable month: week one, revise quant formulas and shortcut methods (R.S. Aggarwal's Quantitative Aptitude is the standard book); week two, drill reasoning types; week three, build vocabulary and do daily comprehension plus mixed practice; week four, one full timed mock a day with honest error review. Free practice lives on IndiaBix and PrepInsta (company-wise), with video solutions on YouTube channels like CareerRide. Keep a small 'mistakes notebook' — the questions you got wrong and why — and reread it the night before your drive. An hour a day is enough; most of your competition won't do even that.
Key Takeaway
An aptitude test rewards preparation, not genius — the patterns repeat, the formulas are countable, and speed is just practice. Start a few weeks before your first walk-in, practise daily under a timer, and pour extra time into your weakest section. Because so many candidates show up with no prep at all, even a modest, steady effort lifts you past most of the room. The goal isn't a perfect score — it's clearing the cutoff cleanly so you earn the chance to prove yourself in the interview rounds that follow.
