How the score is calculated
Correct answers ÷ all 12 questions × 100, rounded to the nearest whole percent. Wrong and unanswered questions earn zero; guessing has no extra penalty. For example, 9 correct out of 12 gives 75%.
The result screen also shows each skill’s correct-answer count. Those are small samples, useful for choosing what to practise, not reliable estimates of general ability. Timed mode allows 8 minutes; untimed mode removes the countdown. Each attempt draws 12 questions from a bank of 48, so two attempts have the same structure and skill mix but different questions. Compare results in the same mode and question-set version.
Choose your next step
These are descriptive score ranges for this exercise. They are not population norms, percentiles, employer pass marks or clinical categories.
0–49% correct
Work through the missed questions without the timer. Use the explanation to identify the rule or calculation you missed.
50–74% correct
Group your errors by skill. Practise the weakest skill with fresh examples before repeating this question set.
75–99% correct
Review the remaining misses and check whether speed or accuracy caused them. Use the same mode when comparing runs.
100% correct
You answered this entire set correctly. Try unfamiliar questions next; a perfect retake may reflect memory of the answers.
Make the correction yourself
Edit twelve sentences drawn from a bank of forty-eight, using standard US written English. Each sentence has one intended spelling, agreement, word-choice or punctuation correction. Make the smallest necessary change and preserve the meaning. This is an editing task, not a multiple-choice quiz.
Read once for meaning and again for mechanics. Check subject-verb agreement, homophones, possession and sentence boundaries separately. The scorer accepts the published minimal corrections, with flexible spacing and straight or curly quotation marks; broader stylistic rewrites will not match.
Make a useful personal comparison
A retake draws different questions from the same bank and avoids the ones you have just seen, so a second score depends far less on remembering answers. Read the explanation for every miss before you go again.
This is unsupervised practice with no identity check. It is not an IQ test, medical assessment, verified certificate or basis for a hiring decision. Question set and scoring version: 2026-09-v2.
