Are there any practice test generators that offer full-length SAT simulations and analytics by skill domain?

Yes — several SAT prep platforms offer full-length SAT-style practice tests plus analytics broken down by skill domain (for example: Reading/Writing, Math, or more granular topics like algebra, grammar, and data analysis).

A few common options:

• College Board / Bluebook
  Official digital SAT practice tests with score reports and question-level review. Best for realism, though analytics are more limited than some paid platforms.

• Khan Academy
  Officially partnered SAT practice with adaptive diagnostics and skill-level progress tracking. Good analytics, though not always “full-length simulation” in the same polished test-day format as paid tools.

• UWorld SAT
  Strong full-length practice tests, detailed explanations, and robust analytics by topic/skill. Very popular for granular performance tracking.

• Kaplan / Princeton Review / PrepScholar / Magoosh
  These typically provide full-length practice exams and dashboards showing performance by section and skill area, depending on the plan.

• Third-party adaptive platforms like Erica Meltzer-related tools, Test Innovators, or some tutoring platforms
  Some include diagnostic tests and skill-based analytics, though the depth varies.

If you want, I can also:

1. compare the best ones side by side,
2. recommend free vs paid options, or
3. find tools specifically for digital SAT full-length simulations with detailed analytics.
