Free SAT practice, 15 minutes a day

Grades 7 to 12 · on the same Teach Me login as math and reading · updated 2026-11-02

Teach Me's SAT subject finds the level of every SAT skill, then practices the ones worth the most points, ten questions a day, with hints that stop before the answer and timed checks at SAT pace. It projects a score out of 1600 and moves it as skills climb. A parent turns it on under Subjects for any child in 7th grade or above; students 13 and up can sign up on their own.

How it works

Levels. Every skill climbs Easy → Medium → Hard, two clean days (right, no hint) at each level. A miss takes a clean day back; "I don't know this yet" parks the skill for the day and brings it back one step easier tomorrow.

Daily set. Ten questions from the skills with the most points left for you, at each skill's level. About 15 minutes; a day that runs long gets one question shorter.

Hints. Hint 1 is the strategy for the skill. Hint 2 knocks out a wrong choice, or gives the first step. Teach me shows a worked example of a different question on the same skill. With AI on, a walkthrough explains the question step by step and stops before the answer.

Test-day check. Two clean days at Hard make a skill ready. The check is timed at SAT pace with no hints; right and on pace means mastered.

Projected score. Built from skill levels and the College Board's domain weights: 200 to 800 per section. An estimate from practice, not an official score.

Reading and Writing: 11 skills

Craft and Structure

• Words in context about 12% of the section — Cover the choices. Use the clues around the blank to predict your own word, then pick the choice closest to it. Precise beats "sort of related."
• Text structure and purpose about 9% of the section — Ask why the author wrote this. Look at what the text does (argues, describes, contrasts, questions), not just what it is about.
• Cross-text connections about 7% of the section — Sum up each author's main claim in a few words first. Then ask how the Text 2 author would react to that specific claim in Text 1.

Information and Ideas

• Central ideas and details about 8% of the section — Say the main idea in your own words before you read the choices. The right answer covers the whole text, not one detail.
• Command of evidence: text about 7% of the section — Restate the claim exactly. The right choice supports that claim, not the topic in general.
• Command of evidence: data about 5% of the section — Each choice needs two things: it is true in the table, and it supports the specific point in the text. Most wrong choices have only one.
• Inferences about 6% of the section — The blank must follow from the text and nothing else. Pick the choice the text forces, not one that is merely possible.

Standard English Conventions

• Boundaries (punctuation) about 13% of the section — Find the subject and verb on each side of the blank. Two full sentences need a period, a semicolon, or a comma plus and/but/so. A comma alone is never enough.
• Form, structure, and sense about 13% of the section — Find what the blank connects to. Match the verb to its subject (skip the words in between), the pronoun to its noun, and the tense to the rest of the text.

Expression of Ideas

• Rhetorical synthesis about 12% of the section — Reread the goal in the question. Pick the sentence that does exactly that goal, even if another one sounds more interesting.
• Transitions about 8% of the section — How do the two ideas connect: same direction, contrast, cause and effect, example, or next step? Pick the transition that matches.

Math: 19 skills

Algebra

• Linear equations in one variable about 8% of the section — Undo operations in reverse order: add or subtract first, then multiply or divide. Do the same thing to both sides.
• Linear functions about 8% of the section — In f(x) = mx + b, m is the change for each 1 unit of x, and b is the value when x = 0.
• Linear equations in two variables about 6% of the section — Slope = change in y ÷ change in x. Parallel lines share a slope; perpendicular slopes are negative reciprocals.
• Systems of linear equations about 7% of the section — Line the equations up and add or subtract them so one variable cancels. No solution means same slope, different intercept.
• Linear inequalities about 6% of the section — Solve it like an equation. Flip the sign only when you multiply or divide by a negative number.

Advanced Math

• Equivalent expressions about 13% of the section — Distribute carefully, especially negatives, then combine like terms. Or test x = 2 in the question and in each choice.
• Nonlinear equations about 12% of the section — Get everything on one side, then factor. The discriminant b² − 4ac tells you how many real solutions there are.
• Nonlinear functions about 10% of the section — Plug in carefully and follow the order of operations: exponents before multiplying. For a parabola, the vertex is at x = −b/(2a).

Problem-Solving and Data Analysis

• Ratios, rates, and units about 3% of the section — Find the rate for one unit first, or set up a proportion with the same units on top and bottom.
• Percentages about 3% of the section — Turn percents into multipliers: 20% off is × 0.8, 8% tax is × 1.08. Multiply the steps; never add the percents.
• One-variable data about 2% of the section — Mean = total ÷ count. Median = the middle value after you sort. When a mean changes, work with totals.
• Probability and two-way tables about 2% of the section — Probability = part ÷ whole. The question tells you the whole: everyone, or only one row or column.
• Two-variable data and models about 2% of the section — In a line of best fit y = mx + b, m is the predicted change in y for each 1 unit of x. Residual = actual − predicted. A fixed percent change each period means an exponential model.
• Samples and margin of error about 2% of the section — A random sample lets you scale its proportion up to the whole population. A margin of error gives a plausible range for the population value, not for individuals. Bigger samples mean smaller margins.
• Studies and experiments about 1% of the section — Random assignment to groups allows cause-and-effect. Random selection from a population lets you generalize to that population. Without one, you lose that conclusion.

Geometry and Trigonometry

• Area and volume about 4% of the section — Write the formula first (the SAT gives you a reference sheet), then plug in. Scaling lengths by k scales area by k² and volume by k³.
• Lines, angles, and triangles about 4% of the section — Triangle angles add to 180°, and so do angles on a straight line. Similar triangles share one scale factor.
• Right triangles and trigonometry about 4% of the section — SOH CAH TOA. Label opposite, adjacent, and hypotenuse from the angle named in the question.
• Circles about 3% of the section — In (x − h)² + (y − k)² = r², the right side is r², not r. Complete the square if the equation is not in that form.

Reading and Writing questions come from 210 original passages and questions written for this practice. Math questions are generated with computed answers at three difficulties, so no two days repeat.
