Concrete errors
See whether an error came from a code, a copied field or a missed condition.
A swapped digit or missed condition can change an entire task. Compare codes, check copied records and apply short instructions in 12 practical questions.
A familiar-looking code can still be wrong. These tasks encourage a deliberate comparison with the reference and a separate check of every condition.
See whether an error came from a code, a copied field or a missed condition.
Each task includes the expected answer and the exact detail that decides it.
Use the same habit when checking orders, transferring records or following a procedure.
There are four tasks in each group. Some require an exact match, while others ask for the changed field or the only entry meeting a rule.
Compare the entire code in order, including digit position, letter case and final characters.
Compare copied values against the source: quantities, dates, locations and statuses.
Apply all the stated conditions together, including size limits and time boundaries.
A correct answer earns one point: up to 12 overall and four per group. This version has no timer; the score reflects accuracy on these tasks, not response speed.
Attention to detail matters when you transfer data, check an order or follow a process. This original BrainApps set asks you to distinguish similar codes, locate changes in copied fields and apply several conditions together. All necessary information is on screen. Your result counts the correct answers in this set and separates three task groups, so you can review the kind of mistake to practise avoiding.
Typical tasks ask you to compare similar information, identify copied errors or follow a rule precisely. Here you check codes, records and short instructions with one correct answer per question.
No. This version is untimed. Your score is the number of correct answers, so take the time you need to compare the information carefully.
Practise separating a record into fields, comparing it with the source and checking the instruction before answering. These habits are useful when handling orders, reports and data entry.
Each correct answer gives one point. You can earn 12 overall and four in each group. The percentage is the proportion correct in this set, not a ranking against other people.
Yes, use the question navigation before submitting. After submission, the saved result contains your choices, the source tables and explanations.
Find the exact character, field or condition you missed. Try checking in two passes: first compare the data, then confirm that your choice answers the question asked.
