Practice tools

Diagnose, drill, then measure again

The same simulator and question bank our students work in. Both come with the group course and the Ultimate package, and each can be bought on its own.
The TestPrep SAT practice test simulator: Reading and Writing module 1, question 7 of 27, with the countdown timer, paired passages and four answer choices
The practice test simulator: timed modules, adaptive routing and the Bluebook tools.

20 full-length practice tests

Module-adaptive tests under real timing, each followed by a breakdown by domain, skill and cause. Twenty is enough to measure after every block of work, from the first weeks of a programme to the last.

About the practice tests
The TestPrep SAT question bank: a Words in Context question with the passage on the left, answer choices on the right and the mark-for-review and answer-eliminator tools
The question bank: choose a skill and a difficulty, then work in the exam layout.

Question bank

Questions tagged by domain, skill and difficulty, so practice lands on the specific gap rather than on general revision. Every question has a worked solution.

About the question bank
TestPrep AI Tutor

A tutor for the questions you got wrong, at any hour

When a practice test ends, pick a question you missed and work through it out loud on a shared whiteboard. The AI tutor does not lead with the answer: it asks you questions until you find where you went wrong, then records what kind of mistake it was.

How the AI tutor works
  • Voice and whiteboard

    Talk it through; it reads your handwriting.

  • Desmos open

    The same calculator as on the exam.

  • Hints before answers

    One step at a time, never skipping ahead.

  • First 2 mistakes free

    No card needed to try it.

Why TestPrep

A method you can inspect, not a claim you have to take on trust

TestPrep Education has prepared students for admissions tests since 2008. What follows is what we actually do, stated plainly enough that you can check whether it is happening.

Diagnostic-first planning

No plan is written before a full-length diagnostic has been taken and its errors classified. The plan is a document you receive.

Section specialists

Math is taught by a mathematician and Reading and Writing by a language specialist. We do not staff generalists across both.

Error analysis, every test

Wrong answers classified by domain, skill and cause. A question missed on timing and one missed on content are different problems.

Progress you can see

Each review compares the current error profile against the previous one, so the question is always whether a specific gap has closed.

You will not find a claim on this site that we are the best, the biggest or the number one anything, or a promised point gain. Score improvement depends on the student's starting point, the hours they put in and the time available.

The method

Two students with the same score can need opposite plans

One is losing points to Advanced Math and running out of time in module 2. The other is fine on Math and dropping marks across Craft and Structure. Same total, opposite work. Averaging them into a standard course wastes most of the hours.
  1. 01

    Diagnostic

    A full-length adaptive-format test under real timing, taken for the data rather than the score.

  2. 02

    Error analysis

    Every wrong answer classified by domain, by skill, and by cause: content, method, misreading, or the clock.

  3. 03

    Study plan

    A weekly plan that spends time in proportion to where the points actually are.

  4. 04

    Live tutoring

    One to one or small group, taught by a specialist in the section being worked on.

  5. 05

    Targeted practice

    Question sets filtered to the flagged skills, at the difficulty band you are failing at.

  6. 06

    Full-length testing

    Spaced, not weekly. A test measures; it does not teach.

  7. 07

    Progress review

    Compare the new error profile with the old one, then rewrite the plan.

  8. Then the loop repeats from step two, on the new profile rather than the old one.

    How error analysis works
What we teach

Both sections, each taught by its own specialist

Eight content domains. Knowing which of them your errors cluster in is most of the work of building a plan.

The exam, briefly

What is the Digital SAT?

Two sections and four separately timed modules: 98 questions in 2 hours 14 minutes plus a 10-minute break, scored 400 to 1600. It runs in College Board's Bluebook app and adapts between modules rather than question by question.

Questions we are asked before people book

Short, factual answers. Where a claim is about exam structure, it comes from College Board.

Start with a diagnostic, then choose the package

One full-length test and an error analysis tell you how big the gap is and where it sits. The number of lessons follows from that.
