I like that it helps to practice with paying attention to detail, but I would like other types of questions to challenge myself
Error Checking Tests
Error checking tests assess a candidate’s ability to identify errors in data sets and assess the correctness of information. They are also known as data checking tests. Candidates are required to complete error checking tests under timed test conditions.

Free example error checking questions
It might be helpful to look at a couple of examples of error checking questions. These will show you what to expect and give you a sense of what’s required to pass. Answers are given below the questions.
Question 1
Which of the five options matches the number on the left?
Question 2
Which of the five options matches the email address on the left?
The answers are A) in both cases.

The tests were well suited to the job that I’ve applied for. They are easy to do and loads of them.Sophie used Practice Aptitude Tests to help pass her aptitude tests for Deloitte. Start your success story
How are error checking tests scored?
You will have to identify deviations in a series of data sets to pass the test. The amount of correctly identified inaccuracies in the allotted time will form your score.
What are error checking tests used for?
Error checking tests are used to evaluate how well and fast you can find flaws in data sets, your attention to detail and thoroughness when analysing information. These data sets may consist of code or alpha-numeric blocks.
What do error checking tests involve?
Error checking tests involve so-called ‘strings’ of data that might have flaws in them. Test-takers will have to quickly identify whether these data sets are the same or not. Promptness is a crucial part of these tests and will have as much weight on your score as the number of correctly identified deviations.
What do error checking tests measure?
Error checking tests assess how well a person can find deviations in certain data sets. The questions themselves aren’t typically hard, but there will likely be a large number of questions in a short time period. That is why your ability to work under pressure will be critical to passing the test.
Where can I practice error checking tests?
Error checking tests require a sharp eye. The best way to train this skill is through consistent practice. You can find practice tests of varying difficulty on our website, alongside tips and guides. They are designed to help you master error checking in exam-like conditions.
Where will I take my error checking test?
Usually, you will take the test online. The recruiter will give you a link to access the test and a certain number of days to complete the test. Sometimes an employer will invite a larger number of candidates to take the test in an assessment centre.
Error Checking Tests Tips
1Practice tests are paramount
There is nothing better than practicing error checking test questions to prepare for the assessment. Ideally, the questions you practice should be composed by chartered occupational psychologists, like the ones on this website.
2Practice under exam conditions
When practising, create a quiet environment. Sit at a desk with paper for working things out, and keep a timer close to you. Psychometric tests can be stressful — simulating exam conditions during practice will make you calmer during the real assessment, and better able to perform under the time pressure.
3Make a revision timetable
Plan your practice and stick to your timetable. Map out how many days you have before your real assessment and organise your time accordingly. Although graduate employers will often give you a time window in which to complete your test, it’s worth knowing that they may also recruit on a first-come-first-served basis. So, while it’s important not to rush into sitting your psychometric test before you are ready, it’s best not to drag out your application process either.
4Review the questions you get incorrect
After completing an error checking practice test, make sure you spend sufficient time reviewing the questions you did not get right. You will learn a lot about your weaknesses and if you have a time/skill issue.
5Read the instructions carefully
Take your time to read all the instructions first. These will give you valuable information, such as the time frame you’re working to. And if you get stuck on one particular part, remember that easier questions may follow: it’s better to skip the ones you don’t know, as you might have extra time to go over them again.
6Don’t panic
If you have spent sufficient time practising questions under timed exam conditions, this should relieve a lot of the anxiety you could experience. Also, make sure to get a good night’s sleep before your real assessment, and always keep a bottle of water with you to keep you hydrated.
7Don’t ask for someone else's help
Employers often retest candidates at assessment centres, which means if you weren’t the one taking the first test, they will find out. It’s also likely they will notice a lack of the skills they’re expecting of you if you actually get the job. There is no point cheating.
8Timing is key to success
As mentioned before, the most challenging aspect of error checking tests is asking the candidates to complete them under strict time constraints. Test publishers typically allow candidates between 15 and 30 seconds to answer each question. It’s important to get used to this time frame before taking the assessment.
9Complete the test publisher practice questions
After reading the instructions you will be presented with some example questions prior to your real assessment starting. These practice questions are typically not timed, so take your time reviewing the format of the test. Take note of where the timer is on the screen, what format the questions are in and where the possible solutions are displayed on the screen.
10Take time off
If you’re taking anything from these tips, it should be practice as much as you can. However, make sure to take some time off after you’ve done the work. You don’t want to take the assessment with a headache from practising too much — once you’re confident in your skills, you should take at least a whole day off beforehand.

Good pace but very small font
All email addresses, so probably could use a little more diversity. Small font was tricky.

Print too small
I liked the test but had to enlarge the screen to read the words as the print was too small, and then had to move the screen to click on the answers.
