An AI SAT tutor that works on the questions you get wrong

1. Find your starting point. A short diagnostic, or a full-length adaptive practice test with the real timing and an easier or harder Module 2.
2. See where points are lost. Results by section, module, content domain, skill and difficulty, plus timing per question.
3. Fix one skill at a time. The plan puts your weakest skills first. Each comes with a short lesson and practice that adapts to you.
4. Learn from every mistake. Open any question you missed and the tutor works through it with you, one step at a time.
5. Check your progress. Take another full-length test and compare skill by skill.

A gym charges a one-time fee of $40 plus $25 per month. Which expression gives the total cost, in dollars, for $m$ months?

Say you chose $65m$. Instead of just marking it wrong, the tutor asks:

Tutor: What would 2 months cost, in real life?

Student: 40 plus 25 plus 25, so 90.

Tutor: And what does $65m$ give for $m = 2$?

Student: 130. Oh, it charges the 40 every month.

The correct answer is $40 + 25m$: the fee is paid once, the monthly cost $m$ times. Testing a simple value like this is a habit that catches many "which expression" mistakes, and the tutor will remind you to use it next time.

For Reading and Writing, the tutor helps you find the evidence in the passage for the right answer, and explains why each wrong choice is tempting but unsupported. For grammar questions (Standard English Conventions), it names the rule, such as how a semicolon joins two complete sentences, and gives you a quick example to check you can apply it. Every Reading and Writing question on the Digital SAT has its own short passage, so it can explain the whole question in one place.

The full-length tests follow the Digital SAT's structure: Reading and Writing (2 modules of 27 questions, 32 minutes each), a 10-minute break, then Math (2 modules of 22 questions, 35 minutes each). Module 2 of each section is easier or harder depending on how you did in Module 1. You get a calculator and reference sheet in Math, mark-for-review, an answer eliminator and a timer for each module.

All questions are written by TutorAura in the Digital SAT format. They aren't official College Board questions, so we report raw scores and don't estimate a scaled score: use the free official tests in Bluebook for that.

• It can't give you an official SAT score or predict one exactly.
• It doesn't contain real past SAT questions.
• It can't replace the official practice tests. Use both: Bluebook for official-style scores, TutorAura for the skill breakdown and help with mistakes.

If you want a schedule, our SAT study plan shows 12-week, 4-week and 2-week versions.
