Why your score is a range, not a number
Your projected score is reported as a range with a stated confidence. That is not hedging — it is the only honest thing we can report.
The marginsLink to the section: The margins
- After one mock: the total carries plus or minus 60 points, each section plus or minus 30. Low confidence.
- After two: plus or minus 45 on the total, plus or minus 25 per section. Moderate confidence.
- After three or more: plus or minus 40 and plus or minus 20. Good confidence.
It stops narrowing there because what remains is calibration error, and watching you sit a fourth mock does not reduce it.
Why we cannot give you a numberLink to the section: Why we cannot give you a number
Converting a raw count into a 400 to 1600 scaled score needs the College Board's equating data. That data is not published, and no third-party platform has it. Every practice score you have ever seen is an estimate built on a table somebody calibrated themselves. The difference between platforms is whether they say so.
How to read itLink to the section: How to read it
Compare the whole range against your target, not the centre. Watch the centre move, not the width — the width narrows on a fixed schedule and that is not progress. What a practice SAT score range actually means covers this properly.
