If you're comparing APUSH prep tools, you've probably landed on Albert.io and Knowt alongside this site. All three use the same official College Board section weights, so the real differences aren't in the math — they're in how the tools are put together. Here's an honest, fact-checked comparison based on each provider's own public pages.
The short answer
All three tools use the same underlying formula: MCQ 40%, SAQ 20%, DBQ 25%, LEQ 15%, per College Board's own 2027 exam weights — see how APUSH scoring works for the full breakdown. The real differences are in account requirements and whether practice questions and scoring live on the same page.
APUSH Score Calculator (this site)
No account, no email, no paywall. Enter your MCQ, SAQ, DBQ, and LEQ scores and get an instant predicted 1–5. This site also has a dedicated free APUSH practice test with real MCQ/SAQ/DBQ/LEQ questions and full answer explanations — on the same site as the calculator, so you can practice and score yourself in one workflow instead of switching between tools.
Albert.io
Albert.io offers a well-regarded free APUSH practice exam (55 multiple-choice questions written by APUSH teacher Tom Richey). The catch: you need to create a free Albert account to view explanations, and the free exam covers multiple-choice only — DBQ, LEQ, and SAQ practice aren't part of that specific free set. Albert also has a separate AP US History Score Calculator, but it's a different tool from the practice exam, not the same page.
Knowt
Knowt's AP United States History Score Calculator covers all sections (MCQ and free-response, including DBQ and LEQ), using the same official weights. It's a calculator, not a practice test, though — Knowt keeps practice questions in a separate "Free-Response Room" and flashcard area, so scoring and practicing happen in different places.

FAQ
Is Albert.io free for APUSH?
Albert.io offers a free multiple-choice APUSH practice exam, but you need to create a free account to view explanations for each question.
Does Knowt have an APUSH score calculator?
Yes. Knowt's AP United States History Score Calculator covers all exam sections using the same official College Board section weights used across most APUSH tools, including this site.
Do these calculators give the same predicted score?
They should be close, since all three use the same official 2027 section weights (MCQ 40%, SAQ 20%, DBQ 25%, LEQ 15%). Small differences can come from how each tool estimates score cutoffs, since College Board doesn't publish exact composite-to-score cutoffs in advance.
Do I need to make an account to use the APUSH Score Calculator on this site?
No. The calculator and the practice test on this site are both free to use with no account, email, or sign-up required.
