How to Prepare for an Aptitude Test in Four Weeks

Most people who fail a placement aptitude test don't fail because the questions are hard. They fail because they run out of time on questions they could have solved, or because they never practised under a clock. The maths in these tests rarely goes beyond what you studied in Class 10. What the test really checks is speed, accuracy and calm.

That's good news, because speed and calm can be trained. Four weeks is enough to make a real difference if you practise a little every day instead of cramming on the last weekend.

First, find out what your test looks like

Aptitude tests used by recruiters usually have three parts: quantitative aptitude, logical reasoning and verbal ability. Some add a technical or coding section, a personality questionnaire, or an essay. The number of questions, the time limit, whether there's negative marking and whether you can go back to earlier questions all vary from company to company, and companies change their pattern from year to year.

So before you plan anything, check the official job notification or your college placement cell for the current pattern. If seniors took the same test last year, ask them what it felt like. Did the time run out? Which section was hardest? That one conversation will tell you more than any generic syllabus.

Day one: take a test before you study

This feels backwards, but it saves you a lot of time. Take one full-length practice test under real conditions: timed, no phone, no calculator unless the actual test allows one. Don't worry about the score.

Afterwards, sort every mistake into one of three groups:

• Didn't know how to solve it. This is a concept gap.
• Knew the method but got it wrong. This is a careless or calculation error.
• Knew it but ran out of time. This is a speed problem.

Most people find that the second and third groups are bigger than the first. That changes how you should spend the next four weeks.

Week 1: rebuild the basics

Spend the first week on the topics that feed into everything else. In quantitative aptitude, that means percentages, ratios, averages and basic number properties. Profit and loss, mixtures, and time and work are mostly percentages and ratios wearing different clothes. If percentages are shaky, everything built on them will be slow.

Alongside this, work on mental calculation. Learn squares up to 30 and cubes up to 15, and get comfortable converting common fractions to percentages (1/8 is 12.5%, 1/6 is about 16.67%, and so on). This isn't about memorising tricks. It's about not stopping for 20 seconds every time you need to divide by 7.

For reasoning, start with the topics that have a clear method: number and letter series, coding-decoding, and blood relations. For verbal, read one editorial or long-form article a day and summarise it in two lines. It sounds slow, but reading comprehension is usually the biggest single block of verbal questions, and reading speed only improves with reading.

Week 2: cover the remaining topics

Now move on to time, speed and distance, simple and compound interest, permutations and combinations, and probability. In reasoning, this is the week for seating arrangements, puzzles, syllogisms and data sufficiency. In verbal, add sentence correction, fill-in-the-blanks and para jumbles.

For each topic, solve around 20 to 30 questions of mixed difficulty. When you get one wrong, don't just read the solution. Close it and solve the question again from scratch the next day. If you can't, the gap is still there.

Keep a mistake notebook. One line per mistake is enough: the topic, what went wrong, and the correct approach. By the end of the month, this notebook will be the most useful thing you own.

Week 3: practise under time pressure

This is where most of the improvement happens. Take sectional tests every day and at least two full mock tests this week. Treat every mock like the real thing.

The most important skill to build now is knowing when to leave a question. Set yourself a rough limit, for example around a minute for most quantitative questions. If you're not close to the answer by then, mark it and move on. Long puzzles and seating arrangements are the usual time traps. They're worth attempting only if you can see the structure quickly.

After every mock, spend at least as long reviewing it as you spent taking it. Look at the questions you got right too: was there a faster way?

Week 4: revise and stay steady

Don't start new topics in the last week. Go through your mistake notebook, redo the questions you got wrong, and take two or three more mocks. Your scores will move up and down. That's normal and doesn't mean you're getting worse.

In the last two days, stop taking full tests. Do light revision, check your formula sheet once, and sleep properly. Tired candidates make careless errors, and careless errors are the cheapest marks to lose.

On the test day

If you're taking the test online from home, check your internet connection, webcam and the test platform's system requirements a day earlier. Read the instructions on the first screen properly, especially anything about negative marking and section time limits.

During the test, make a first pass and answer everything you're confident about. Then come back to the questions you marked. If there's negative marking, don't guess blindly. If there isn't, never leave a question blank.

A note on "shortcut tricks"

You'll find plenty of videos promising tricks that solve any question in five seconds. Some of them are genuinely useful, like the digit-sum check for multiplication or using options to work backwards. But a trick you don't fully understand will fail you the moment the question is slightly different. Learn the standard method first. Then pick up shortcuts for question types you see often.

Four weeks won't make anyone a maths genius, and it doesn't need to. It's enough time to stop losing marks to panic and the clock, and for most people that's the difference between clearing the cut-off and missing it.
