Aptitude losses come from concept gaps, slow methods, reading errors, selection and time pressure. Topic scores alone cannot distinguish which intervention will work.

A practical method for diagnosing placement aptitude errors

Rework missed and slow items, tag the cause, and calculate loss patterns across several timed sets. Practise the leading cause in isolation, then retest it in a mixed company-style assessment.

Do not memorise answer patterns from leaked material or assume every employer uses the same test. Follow the authorised current assessment information.
