starp calculates your result from the number of correct answers using a fixed scoring table. The same correct-answer total produces the same current score on the current test.
First, check the answers
Each test contains 30 questions with defined solutions. A correct answer contributes one to the total. The overall mapping uses that total rather than a separate speed bonus or a different weight for each reasoning domain.
The continuous 25-minute deadline controls how long you have to respond. Finishing early does not add points to the scoring table.
Then apply the mapping
| Correct answers | Current indicative score |
|---|---|
| 0 of 30 | 42 |
| 20 of 30 | 90 |
| 21 of 30 | 95 |
| 22 of 30 | 100 |
| 23 of 30 | 104 |
| 24 of 30 | 109 |
| 30 of 30 | 144 |
Every additional correct answer increases the score. The increments are not identical at every step, so a simple percentage multiplied by a constant does not reproduce the table.
Where the scale comes from
The mapping was calibrated using 12,700 simulated completed assessments. Their 381,000 modeled responses were held fixed while the score conversion was adjusted. The resulting scores total 1,270,000, giving that group an average of exactly 100.
That mean belongs to the calibration group. The system does not change each visitor's score to force every future group to average 100. Simulation-based calibration also does not establish a population percentile or a clinical error margin.
Read the skill profile alongside the score
The report separately shows correct-answer percentages for patterns, spatial thinking, logic and numbers. Two people can share the same total while having different domain profiles.
Use the overall score as a summary and the explanations as the route into the actual reasoning. The About page describes the current method; this guide explains how its main parts fit together for a test taker.
