Which test, which tool
| You're holding | Use | Data basis |
|---|---|---|
| A scored digital SAT practice test | SAT Score Calculator | Official practice-test ranges + official percentiles |
| An ACT practice test (2025+ or older) | ACT Score Calculator | Official practice-form tables + official National Ranks |
| AP practice MCQ + FRQ self-scores | AP Score Calculator | Official structures; cutoffs are third-party estimates, labeled as such |
| IB subject grades + TOK/EE | IB Grade Calculator | Official core-points matrix and failing conditions |
| A-level / BTEC / IB results for UK admission | UCAS Points Calculator | Official UCAS tariff tables |
Our rule for exam numbers
Standardized-test scoring is where calculator sites cut corners: the internet is full of "digital SAT conversion charts" that College Board never published. Our rule is simple —every number needs an official source. When the official data is a range (SAT practice-test scoring), you get the range. When it's exact (ACT's practice-form tables, both tests' percentiles), you get the exact figure with its citation. When only third-party estimates exist (AP cutoffs), the page will say "estimate" in plain sight. Test scores drive real decisions; you deserve to know how solid each number is — and because every table on these pages loads from a sourced data file, an official update refreshes the whole page at once instead of leaving stale numbers behind. For everything on the transcript side — course grades, weighted averages, GPA — head to thegrade tools and GPA toolshubs.
Frequently asked questions
Can these calculators predict my exact SAT or ACT score?
No tool honestly can — both exams equate each test form separately, and the digital SAT is adaptive on top of that. What these calculators do is apply the official practice-form conversions and official percentile tables, clearly labeled, so your estimate has a defensible source instead of an invented chart.
Which test do these tools cover?
SAT (digital, with official practice-test score ranges and percentiles), ACT (enhanced 2025 format plus the legacy pre-2025 test), AP (16 subjects with honestly-labeled cutoff estimates), IB (diploma points with the full pass check) and UCAS tariff points.
Where do the numbers come from?
Every conversion and percentile is loaded from a data file citing its official source — College Board scoring guides and percentile research for the SAT, ACT's official practice-form tables and National Ranks for the ACT. When only an estimate exists, the page says so rather than presenting it as exact.
How often do exam score tables change?
Percentile tables refresh annually (SAT in the fall, ACT National Ranks each September), and each real test form carries its own equating. We update the data files on those cycles; because the pages are data-driven, a table update refreshes every number on the page at once.
