The short answer
To do your best on an aptitude test, find out exactly which test you will take, practice its question types at the real pace, and go in with a plan for time: move on from questions that stall you and come back if there is time. Most people lose points to an unfamiliar format and the clock rather than to hard questions, and both improve with a few days of timed practice.
Nine tips that actually help
1. Find out which test it is
Read the invitation and the employer careers page. A named test, such as CCAT, Wonderlic or SHL, tells you the format and timing to practice.
2. Start with a timed sample
Take a free sample before studying. Your results show which question types need the most work, so you do not waste time on what you already do well.
3. Practice at the real pace
Untimed practice builds the wrong habits. Work out the seconds per question (on a Wonderlic-style test, 12 minutes for 50 questions is about 14 seconds) and practice at that speed.
4. Learn the common question types
Number series, percentages, true or false or cannot say, shape sequences and simple deductions repeat across tests. Recognizing the type saves most of the thinking time.
5. Plan to move on
Decide in advance how long you will spend before skipping a question. One stuck question can cost three easy ones.
6. Check the rules on calculators and scrap paper
Some tests allow a calculator and some do not; Wonderlic and Criteria both say theirs do not. The instructions will say. Practice the way you will take the test.
7. Take full-length mocks
Ten questions feel different from fifty. Two or three full timed mocks make the real test feel familiar.
8. Prepare the day before
Check your device, internet connection and the login link. Sleep well: fast tests are sensitive to tiredness.
9. On the day
Choose a quiet place, close other tabs, read each question to the end and keep an eye on the clock without staring at it.
Work out your pace from the real format
Pace is the number most people never calculate. Divide the time by the number of questions, and practice at that speed:
- Wonderlic: 50 questions in 12 minutes (Wonderlic), about 14 seconds each.
- CCAT: 50 questions in 15 minutes (Criteria), about 18 seconds each.
- Graduate-style aptitude tests: Prospects says you will often have about one minute per multiple-choice question, with tests running roughly 15 to 60 minutes (Prospects).
The two kinds call for different habits. At 14 to 18 seconds, you are recognizing question types and answering on instinct backed by practice. At a minute per question, you are reading a table or passage carefully and checking your working.
Neither Wonderlic nor Criteria expects you to finish. Wonderlic says test takers are not expected to complete all the questions in the time (Wonderlic FAQ), and Criteria says fewer than 1% of candidates answer all 50 (Criteria).
Guessing and skipping: the rules differ
Whether to guess is one of the most common questions, and the honest answer is that it depends on the test.
No penalty for wrong answers. Criteria says the CCAT has no penalty for wrong answers (Criteria). On a test like that, an informed guess is always better than a blank.
Scoring that accounts for guessing. Wonderlic says its cognitive scoring weights each question by difficulty and by the impact of guessing (Wonderlic). It also advises candidates not to spend too long on any one question and not to skip around hoping to come back (Wonderlic FAQ).
Everything else: read the instructions on the first screen. They usually say whether you can go back, whether wrong answers cost marks, and whether the test ends when the time runs out or when you finish a section.
A good default: if you can rule out even one option, choose from the rest and keep moving.
Build the core skills
A small set of skills covers most aptitude test questions. If your free sample shows a weak spot, these guides go through the method, the traps and practice questions:
- Numbers: percentage questions, ratio questions and speed, distance and time. Calculators are not allowed on some fast tests; Wonderlic and Criteria both say so for theirs (Wonderlic FAQ, Criteria).
- Patterns: number series questions, the seven patterns behind most series.
- Logic: syllogisms and deductive reasoning examples, for "which must be true" questions.
- Workplace judgement: situational judgement test examples, if your test includes scenarios.
Spend most of your time on your one or two weakest areas. Polishing what you already do well feels productive, but it moves your score less.
A one-week plan
Day 1: baseline. Take a free timed sample of the test you will sit. Note your score, where you ran out of time, and which question types went wrong.
Day 2: weakest skill. Read the guide for your weakest type and work through its practice questions untimed. Then do ten more at the real pace.
Day 3: second weakest skill. Same routine for the next type.
Day 4: first full mock. One complete timed test in a quiet room, in one sitting. Review every miss and label it: method, misread or time.
Day 5: fix what the mock showed. Short timed sets of the question types you missed most.
Day 6: second full mock. Compare it with day 4. Look at pace as well as score: did you reach more questions?
Day 7: rest and set up. Light review only. Check your device, connection and login link, and plan when you will take the test.
With fewer days, keep the order and squeeze it: baseline, weakest skill, one full mock.
If you only have one day
Do three things, in this order:
- Take a timed sample to see the format and the pace. This alone removes much of the shock of the real test.
- Learn your plan for time. Know how many seconds you have per question and decide when you will move on.
- Fix one thing. Pick the question type that cost you most and read its guide. One clear method is worth more than skimming five.
Then stop and sleep. A tired brain loses more points on a fast test than a last-minute cram can gain.
Handling nerves on the day
Most people feel some nerves before a test that matters. A few practical steps help:
- Know what to expect. Practice is the best remedy for test nerves, because nothing on screen is new.
- Use the first screen. Read the instructions slowly and take a few slow breaths before you start the clock.
- Expect to not finish. On fast tests, running out of time is normal and built into the design. Seeing unanswered questions at the end does not mean you did badly.
- Let a bad question go. One question you could not do says nothing about the next one. Choose an answer and move on.
- Plan for problems. If the connection drops or the page freezes, contact the employer straight away and explain what happened.
What practice can and cannot do
Practice makes the format familiar and helps you find a sustainable pace, which is where most avoidable points are lost. It will not change the underlying ability a test measures overnight, and no honest site can promise a result on a real test. The aim is to make sure your score reflects what you can actually do.

Frequently asked questions
How long should I practice before an aptitude test?+
Even two or three days of focused, timed practice helps. A week of short daily sessions is better than one long session the night before.
Is it better to guess or leave a question blank?+
It depends on the test, so check the instructions. Criteria says the CCAT has no penalty for wrong answers, while Wonderlic says its scoring accounts for guessing.
Can you fail an aptitude test?+
There is rarely a fixed pass mark. Employers compare your result with a target for the role, often alongside your application and interviews.
What if I run out of time?+
Most people do on fast tests. Focus on answering accurately at a steady pace rather than finishing.
How do I prepare for an aptitude test in one day?+
Take a timed sample to learn the format, work out your seconds per question, and study the one question type that cost you most. Then sleep.
Can I use a calculator in an aptitude test?+
It depends on the test. Wonderlic and Criteria both say calculators are not allowed on their timed cognitive tests. Other tests say in their instructions.
Are aptitude test practice questions the same as the real ones?+
No. Honest practice tests use original questions in a similar format and at the same pace. That is what builds the skill; the real items are not public.
